Best Buy vs Costco vs Target vs Amazon for iPhone 17 Retailer Trade-In in the US 2026: Which Retailer Gives the Biggest Effective Discount?

Retailer-side iPhone 17 trade-in programs are not a monolithic mechanic. Credit value, credit format, condition-grading strictness, and stacking rules differ across Best Buy, Costco, Target, and Amazon in ways that materially change the effective discount for different US shopper profiles. Here is the head-to-head, with real-world credit numbers for iPhone 12 through iPhone 16 traded toward iPhone 17.

The short answer, upfront

For US shoppers buying iPhone 17 in 2026 with a retailer-side trade-in:

• Best Buy typically leads on retailer credit value across iPhone 13 through iPhone 16 traded in good condition, and is the most flexible on immediate credit realization.
• Costco wins for Costco Executive Members buying iPhone 17 Pro on a new carrier line via Costco Wireless Advocate, where the carrier trade-in plus Costco Shop Card bonus plus Executive 2% rebate stack produces the largest total effective discount.
• Target is the smallest of the four in nominal trade-in credit but Q4 Circle bonuses close the gap, particularly during Black Friday and Cyber Monday windows.
• Amazon trails Best Buy by USD 20 to 65 on nominal credit but is the frictionless path for Amazon-first shoppers who plan to buy iPhone 17 unlocked from Amazon and pay with the Amazon Rewards Visa (5% back for Prime members).

As of 2026-07-28, the retailer-side trade-in market has softened somewhat from Q4 2025 peak levels; expect Q4 2026 promotional stacking to reintroduce meaningful bonuses at Best Buy and Target in particular.

ShopBack is the US cashback and rewards app. Sign up free at shopback.com, click through to Best Buy, Costco, Target, or Amazon via the ShopBack merchant page, and earn a percentage back as cashback on your iPhone 17 purchase (post-trade-in) on top of retailer loyalty and credit card points. Rates change monthly and are shown live on each merchant page.

The retailer trade-in program landscape in 2026

The four major US mass-market retailers with active iPhone trade-in programs are structurally different. Understanding the structure of each is prerequisite to picking the right one for your specific US-shopper profile.

Best Buy Trade-In. Best Buy operates its retailer trade-in as a first-party program with in-store and online (mail-in) submission options. In-store trade-in has the largest operational advantage: a Best Buy Blue Shirt or Geek Squad agent grades the device on the spot, extends a Best Buy e-gift card credit, and can apply that credit directly to the iPhone 17 purchase in the same transaction. Online trade-in requires mail-in with post-inspection final grading, which can revise the initial online estimate downward (or up in rare cases). My Best Buy members access baseline trade-in values; My Best Buy Plus and My Best Buy Total members access enhanced trade-in bonuses of USD 50 to 200 on select devices during promotional windows.

Costco Wireless Advocate (via Verizon, AT&T, or T-Mobile). Costco does not run a standalone iPhone trade-in program at retail; instead, Costco Wireless Advocate is a kiosk inside Costco warehouses that sells iPhone 17 as a new line activation with the partnered carrier, and the carrier's trade-in program is what applies. On top of the carrier's trade-in credit (delivered as 24 to 36 months of monthly bill credit), Costco layers a Costco Shop Card bonus (USD 100 to 300 depending on the promo cycle) available to any Costco member. Costco Executive Members also earn 2% annual rebate on qualifying Costco spend. The result is a three-layer stack (carrier bill credit + Costco Shop Card + Executive rebate), but the mechanic is fundamentally different from Best Buy or Amazon: you must open a new carrier line for the full term or forfeit remaining credit.

Target Trade-In. Target operates its retailer trade-in through a third-party partner (historically CExchange). The submission is either in-store at a Target Guest Services counter (a Blue Shirt or Target team member packages the device for mail-in to CExchange) or online (customer mails the device directly to CExchange). Credit is delivered as a Target GiftCard, redeemable at Target on any purchase within 4 years of issuance. Target Circle members earn 1% back on qualifying Target purchases plus periodic Circle bonus offers (concentrated in Q4). Target RedCard members save an additional 5% off Target purchases. Target Circle 360 (formerly Target Shipt) offers free 2-hour delivery and additional shopping benefits.

Amazon Trade-In. Amazon operates its retailer trade-in as a mail-in-only program (no physical store option since Amazon does not have a comparable physical retail footprint for electronics trade-in). The device is inspected at Amazon's fulfillment center after mail-in; credit is issued as an Amazon Gift Card usable at Amazon.com. Amazon Trade-In has periodic promotional bonuses during Prime Day (July), Prime Big Deal Days (October), and Black Friday to Cyber Monday (November) that add USD 25 to 100 in bonus credit on qualifying iPhone trade-ins.

Trade-in credit values by traded iPhone model in 2026-07

Approximate credit for good-condition, working iPhone with battery health above 80%, no significant screen or body damage. Values captured 2026-07-28.

Traded-In Model	Best Buy (e-gift card)	Costco Wireless Advocate (carrier bill credit total over 24-36 months)	Target (Target GiftCard)	Amazon (Amazon Gift Card)
iPhone 12 (128GB)	$90 to $155	$100 to $180	$60 to $120	$80 to $140
iPhone 12 Pro (256GB)	$130 to $195	$180 to $260	$110 to $175	$115 to $185
iPhone 13 (128GB)	$175 to $240	$200 to $300	$150 to $210	$160 to $225
iPhone 13 Pro (256GB)	$260 to $330	$340 to $440	$220 to $290	$225 to $305
iPhone 14 (128GB)	$220 to $290	$260 to $360	$195 to $265	$205 to $275
iPhone 14 Pro (256GB)	$285 to $340	$350 to $500	$250 to $315	$235 to $295
iPhone 15 (128GB)	$335 to $415	$430 to $560	$310 to $385	$305 to $375
iPhone 15 Pro (256GB)	$450 to $550	$500 to $700	$385 to $480	$380 to $460
iPhone 16 (128GB)	$485 to $600	$610 to $780	$445 to $555	$430 to $535
iPhone 16 Pro (256GB)	$615 to $750	$700 to $900	$545 to $660	$525 to $640
iPhone 16 Pro Max (512GB)	$780 to $965	$850 to $1,100	$685 to $840	$665 to $815

Notes on the table: Costco values are total bill credit over 24 to 36 months on a new carrier line via Costco Wireless Advocate; the nominal number is not directly comparable to Best Buy's immediate e-gift card credit. Amazon values assume the device passes Amazon's post-mail-in inspection at the submitted condition tier. Target values reflect the base program without Q4 Circle bonuses.

Best Buy iPhone 17 trade-in: the flexibility play

Best Buy's iPhone 17 trade-in is the flexibility-first US-shopper option. Three structural advantages:

1. Immediate credit realization. Walk into a Best Buy store, hand over your old iPhone at the Geek Squad or Blue Shirt counter, and the credit is applied to your iPhone 17 purchase in the same transaction. No mail-in wait, no post-inspection revision risk, no carrier commitment. If you buy iPhone 17 Pro at USD 1,099 with a USD 500 iPhone 15 Pro trade-in credit, you pay USD 599 net at the register.

2. In-store condition grading with walk-away option. If the Best Buy agent grades your device below the tier you expected (say, from Good to Fair), you can walk away without submitting the trade-in. This is a meaningful risk-reduction versus Amazon's mail-in inspection, where a downgrade happens after Amazon has the device and the customer's leverage is limited.

3. My Best Buy Plus and Total member bonuses. My Best Buy Plus (USD 49.99/year in 2026) and My Best Buy Total (USD 179.99/year in 2026) members receive enhanced trade-in credit on promotional windows, typically USD 50 to 200 above the standard credit on iPhone 13 Pro through iPhone 16 Pro Max devices. Total members also get free Geek Squad Protection 2-year coverage and 20% off Geek Squad services.

Best Buy iPhone 17 buying stack:

1. Sign up for ShopBack (free) at shopback.com/signup.
2. Click through from shopback.com/best-buy to Best Buy to reserve the iPhone 17 for in-store pickup or ship-to-home.
3. Bring your old iPhone to Best Buy for in-store trade-in at Geek Squad counter.
4. Trade-in credit is applied to iPhone 17 purchase at checkout.
5. Pay with the My Best Buy Visa (5x points on Best Buy purchases, no annual fee) or a general travel-and-purchase credit card (Chase Sapphire Preferred 2x on travel; Amex Gold 4x on US dining and US supermarkets, 1x elsewhere).
6. ShopBack cashback tracks on the net post-trade-in purchase price.

Best Buy trade-in credit is one-time and cannot be split across multiple purchases. If your trade-in credit exceeds the iPhone 17 purchase price, the balance is applied to accessories, cases, chargers, and other Best Buy inventory in the same transaction, or is issued as a Best Buy e-gift card for future use.

Costco iPhone 17 (via Wireless Advocate): the Executive Member play

Costco's iPhone 17 offering is structurally different from the other three retailers because Costco does not directly sell iPhone 17 as a retail product. Instead, Costco Wireless Advocate is a kiosk inside Costco warehouses (US and select Puerto Rico locations) operated in partnership with Verizon, AT&T, and T-Mobile. The kiosk sells iPhone 17 on new carrier line activations, and the carrier's trade-in program is what applies.

Three-layer Costco stack:

Layer 1: Carrier trade-in bill credit. The partnered carrier's trade-in program applies, delivering bill credit spread over 24 to 36 months of continued carrier service. On iPhone 15 Pro trade-in toward iPhone 17 Pro on a new Verizon line, the bill credit typically runs USD 500 to 700 over 36 months as of 2026-07-28.

Layer 2: Costco Shop Card bonus. Costco Wireless Advocate provides a Costco Shop Card bonus on top of the carrier's trade-in on qualifying new line activations. The bonus varies by promo cycle: typical USD 100 to 300 on iPhone 17 Pro activations, higher during Costco's holiday promotional windows. Costco Shop Card is redeemable at any Costco warehouse or Costco.com on any purchase.

Layer 3: Executive Membership 2% annual rebate. Costco Executive Members (USD 130 per year in 2026) earn 2% back on qualifying Costco purchases including Costco Wireless Advocate iPhone purchases, capped at USD 1,250 annual rebate. On an iPhone 17 Pro purchase at USD 1,099 to 1,399, Executive rebate contributes USD 22 to 28.

Costco iPhone 17 buying stack:

1. Verify Costco Membership (Gold Star at USD 65 or Executive at USD 130 in 2026).
2. Sign up for ShopBack (free) at shopback.com/signup.
3. Click through from shopback.com/costco to costco.com to research Wireless Advocate current promotions (some Wireless Advocate purchases track online; in-warehouse purchases may not).
4. Visit the Costco Wireless Advocate kiosk in your local warehouse; the agent walks you through Verizon, AT&T, or T-Mobile plans and iPhone 17 configurations.
5. Trade in your old iPhone at the kiosk (device is inspected on the spot).
6. New carrier line is activated; iPhone 17 is issued.
7. Costco Shop Card bonus is mailed to your Costco account within 30 to 60 days.
8. Carrier trade-in bill credit begins on your first monthly bill and continues for 24 to 36 months.
9. Executive Membership 2% rebate accrues at year-end.

Costco iPhone 17 pathway is optimal for US shoppers who are:

• Costco Executive Members already
• Buying iPhone 17 Pro or iPhone 17 Pro Max
• Willing to commit to a new Verizon, AT&T, or T-Mobile line for 24 to 36 months
• Not planning to switch carriers or upgrade phones sooner

If you are already on Verizon, AT&T, or T-Mobile with a line you want to keep, the Costco Wireless Advocate path may require you to add a new line rather than upgrade an existing one; check the current carrier promotion terms.

Target iPhone 17 trade-in: the RedCard plus Circle play

Target's iPhone 17 trade-in is the smallest of the four on nominal credit, but Target's overall shopping ecosystem (RedCard 5%, Circle 1%, Q4 Circle bonuses, free 2-day shipping for RedCard members) makes it the strongest option for shoppers who are already deep in the Target habit.

Target iPhone 17 stack layers:

Layer 1: Target Trade-In credit. iPhone 12 through iPhone 16 trade-in credit ranges USD 60 to 660 in Target GiftCard credit (see table above). Credit is issued after mail-in inspection by CExchange (Target's trade-in partner); typical processing time is 5 to 10 business days from mail-in receipt.

Layer 2: Target Circle bonus (Q4 promotional windows). During Q4 (October to December), Target Circle members occasionally get bonus offers on electronics category purchases: USD 50 to 200 bonus GiftCard on iPhone purchase of USD 800+, or 5x Circle earnings on the purchase, or free accessories bundle. These promos are announced weekly during Q4; watch the Target Circle app in October and November.

Layer 3: Target RedCard 5% discount. RedCard (credit or debit) saves 5% on Target purchases automatically at checkout. On an iPhone 17 Pro purchase at USD 1,099, RedCard saves USD 55.

Layer 4: Target Circle 360 membership. Target Circle 360 (USD 99/year, formerly Target Shipt) provides free same-day delivery on Target purchases over USD 35, plus early access to Circle deals. Not directly relevant to iPhone 17 pricing but relevant for the broader Target-shopper ecosystem.

Target iPhone 17 buying stack:

1. Sign up for ShopBack (free) and Target Circle (free).
2. Click through from shopback.com/target to Target.
3. Complete the iPhone trade-in via CExchange (mail-in or in-store Guest Services drop-off).
4. Wait 5 to 10 business days for Target GiftCard credit to arrive by email.
5. Apply Target GiftCard credit to the iPhone 17 purchase online or in-store.
6. Pay with Target RedCard for 5% instant discount.
7. Circle earns 1% back on qualifying purchases; Q4 bonus if applicable.
8. ShopBack cashback tracks on the net purchase.

Target iPhone 17 works best when: you are a RedCard holder already, you shop Target regularly (Circle 1% compounds), and you can wait 5 to 10 days for trade-in credit issuance rather than needing immediate credit realization. Best for the Target-first US shopper.

Amazon iPhone 17 trade-in: the Amazon-first shopper play

Amazon Trade-In is the frictionless path for shoppers who buy most of their electronics from Amazon anyway. Mail-in a device, receive Amazon Gift Card credit, apply the credit to an iPhone 17 purchase at Amazon.com.

Amazon iPhone 17 stack layers:

Layer 1: Amazon Trade-In credit. iPhone 12 through iPhone 16 trade-in credit ranges USD 80 to 815 as Amazon Gift Card (see table above). Amazon operates a firmer post-inspection review than Best Buy or Target: if the device is graded below the submitted tier, Amazon issues a lower credit than the initial online estimate. The customer can accept the revised credit or request return of the device (though Amazon typically returns declined devices only after a specific request, and the process takes 3 to 5 business days).

Layer 2: Prime Day and Black Friday bonuses. During Prime Day (July), Prime Big Deal Days (October), and Black Friday to Cyber Monday (November), Amazon Trade-In runs bonus promotions adding USD 25 to 100 extra gift card credit on qualifying iPhone trade-ins.

Layer 3: Amazon Rewards Visa (Prime members). Amazon Rewards Visa (issued by Chase) earns 5% back on Amazon purchases for Prime members, 2% back at gas stations, restaurants, and drugstores, 1% back everywhere else. No annual fee. On a USD 1,099 iPhone 17 Pro purchase at Amazon, Amazon Rewards Visa earns USD 55 back in Amazon rewards points.

Layer 4: Amazon Prime shipping. Prime shipping ships iPhone 17 free 2-day (or same-day in select US markets). Not a discount but a real value versus a Best Buy in-store pickup that requires driving to the store.

Amazon iPhone 17 buying stack:

1. Sign up for Amazon Prime (USD 139/year in 2026) if not already a member.
2. Sign up for ShopBack (free) at shopback.com/signup.
3. Complete Amazon Trade-In of your old iPhone via the Amazon.com/tradein page.
4. Mail the device with the prepaid shipping label; wait 7 to 14 business days for inspection and gift card issuance.
5. Click through from shopback.com/amazon to Amazon to purchase iPhone 17.
6. Apply Amazon Gift Card credit at checkout.
7. Pay balance with Amazon Rewards Visa for 5% back (Prime members).
8. ShopBack cashback tracks on the net purchase.

Amazon iPhone 17 works best when: you are an Amazon Prime member, you use the Amazon Rewards Visa for Amazon purchases, you are patient with the 7 to 14 day mail-in trade-in cycle, and you plan to buy iPhone 17 unlocked from Amazon rather than through a carrier.

Four buyer profiles, four different recommendations

Profile 1: The Costco Executive Member family of four buying iPhone 17 Pro on a new carrier line. Best fit: Costco Wireless Advocate on a Verizon or AT&T new line. Total stack (carrier trade-in bill credit + Costco Shop Card bonus + Executive 2% rebate + ShopBack cashback if tracked online) produces the largest effective discount over 36 months.

Profile 2: The Best Buy loyalty shopper with My Best Buy Plus who wants iPhone 17 unlocked and immediate. Best fit: Best Buy in-store trade-in at Geek Squad counter, with My Best Buy Plus bonus applied. Immediate credit realization; walk out with iPhone 17 the same day; no carrier commitment.

Profile 3: The Target RedCard holder who shops Target weekly. Best fit: Target Trade-In during Q4 with a Circle bonus offer active. Nominal trade-in credit is smaller than Best Buy but the RedCard 5% + Circle 1% + Q4 bonus + ShopBack cashback stack closes most of the gap, and Target's shopping ecosystem outperforms Best Buy on non-iPhone recurring purchases.

Profile 4: The Amazon Prime shopper with Amazon Rewards Visa. Best fit: Amazon Trade-In mail-in, then buy iPhone 17 unlocked at Amazon.com with Amazon Gift Card credit plus 5% Amazon Rewards Visa. Frictionless if you are already an Amazon-first shopper; not the largest nominal credit but the smoothest process for the Amazon-native profile.

The cashback stack: ShopBack layers over any of the four

ShopBack cashback stacks on iPhone 17 purchases across all four major US retailers. The layering:

1. Sign up free at ShopBack. shopback.com/signup.
2. Click through from the ShopBack merchant page. shopback.com/best-buy, shopback.com/costco, shopback.com/target, or shopback.com/amazon. Cashback rate is shown at click-through.
3. Complete the iPhone 17 purchase on the retailer's site or in-store. In-store purchase tracking varies by retailer; online-first purchases track most reliably.
4. Cashback confirms 30 to 90 days post-purchase. Withdraw to a US bank account, PayPal, or supported gift cards.

Total return per US shopper on a USD 1,099 to 1,399 iPhone 17 purchase after trade-in typically nets to USD 500 to 900 in effective total discount when the trade-in, retailer loyalty, credit card cashback, and ShopBack cashback are stacked.

When retailer trade-in beats carrier trade-in (and when it doesn't)

Retailer trade-in wins when:

• You want iPhone 17 unlocked, not carrier-locked.
• You do not want to commit to a specific carrier for 24 to 36 months.
• You value immediate credit realization at purchase (Best Buy in-store).
• You may switch carriers, downsize your phone plan, or upgrade to iPhone 18 before the carrier's trade-in term ends.
• You have an unlocked device or a device from a carrier not aligned with your target new line.

Carrier trade-in wins when:

• You are committed to staying on Verizon, AT&T, or T-Mobile for at least 36 months.
• You are opening a new line (adding a family member, business line, or dependent line).
• The carrier's total bill credit exceeds the retailer's nominal credit by more than USD 250, and you value that dollar amount over flexibility.
• You are buying iPhone 17 Pro or Pro Max where carrier bill credit can reach USD 1,000+ on select flagship trade-ins with new lines.

The carrier-vs-Best Buy iPhone 17 trade-in article covers the Verizon vs AT&T vs Best Buy comparison in more detail.

What NOT to do

• Do not mail in an iPhone to Amazon Trade-In with battery health below 80% and grade it as Good. Amazon's post-inspection will downgrade to Fair or lower; you receive less than the online estimate and may struggle to recover the device.
• Do not commit to a Costco Wireless Advocate new line if you are likely to switch carriers within 36 months. Forfeiting remaining carrier trade-in credit if you cancel early undoes the primary Costco Wireless Advocate value.
• Do not skip the ShopBack click-through step. Cashback on a USD 1,099 iPhone 17 Pro purchase (post-trade-in) is USD 15 to 45 depending on the retailer's current ShopBack rate; that is 3 minutes of setup for a real dollar return.
• Do not use Target Trade-In if you need immediate credit. Target's CExchange mail-in workflow takes 5 to 10 business days after receipt for GiftCard credit issuance; not suitable if you want iPhone 17 today.
• Do not use Best Buy retailer trade-in if you plan to stack it with a carrier trade-in on the same iPhone 17 purchase. Retailer and carrier trade-in are typically mutually exclusive on a single iPhone.
• Do not accept the initial online trade-in estimate at any retailer without confirming your device condition matches the submitted tier. In-store confirmation (Best Buy) or careful condition assessment (Amazon, Target, Costco) protects against post-inspection downgrade.

Key takeaways

• Best Buy leads on retailer credit value for iPhone 13 through iPhone 16 traded in good condition; USD 20 to 90 above the other three retailers
• Costco Wireless Advocate wins on total effective discount for Executive Members on iPhone 17 Pro new-line activations over 36 months
• Target's smaller nominal trade-in credit is offset by Q4 Circle bonuses, RedCard 5%, and Circle 1%
• Amazon Trade-In is the frictionless path for Amazon Prime members with Amazon Rewards Visa (5% back for Prime members)
• Best Buy in-store trade-in delivers immediate credit at the counter; Amazon and Target mail-in require 5 to 14 days
• Costco Executive Membership costs USD 130 per year but breaks even on typical family US Costco spend
• ShopBack cashback stacks on iPhone 17 purchases at all four retailers via shopback.com/best-buy, shopback.com/costco, shopback.com/target, and shopback.com/amazon
• iPhone 12 (128GB) good-condition trade-in: USD 60 to 180 across the four retailers
• iPhone 16 Pro (256GB) good-condition trade-in: USD 525 to 900 across the four retailers
• Retailer trade-in wins on flexibility and immediate credit; carrier trade-in wins on nominal credit when you commit to 36 months on the same carrier
