Is there a checklist for buying online to get the best deal?

Yes, and it fits on one screen. These ten checks cover what usually decides whether an online order is a good deal or just looks like one. Run them in order, because the early checks decide which store you buy from, and the last check decides how much that order really costs you.

1. Same item, everywhere. Match the brand, model number, size, color and quantity before you compare prices. A lower price on a different variant is not a deal.
2. Who is selling it. On big marketplaces, an item can be sold by the store itself or by a third-party seller. On Walmart.com, for example, Marketplace seller items may be returned within 30 days, compared with 90 days for most items sold by Walmart, according to Walmart's Standard Return Policy.
3. Total delivered price. Add shipping, tax and any handling fee. A cheap item with paid shipping can cost more than a pricier one that ships free.
4. Price-match and price-drop rules. Some stores adjust after you buy and some do not. Target's Price Match Guarantee allows a request within 14 days of purchase if Target's own price drops; Walmart.com does not adjust after purchase.
5. Return window and return cost. Note how many days you have and who pays return shipping.
6. Delivery time. If you need it by a date, the cheapest option may not arrive in time.
7. Sale timing. If a big sale is a few weeks away and the item is not urgent, waiting can be the better deal.
8. A valid promo code. Use a code from the store itself or from the store's ShopBack page, and confirm it applied on the final screen.
9. How you pay. Use the card or payment method you already use for purchases, and keep the receipt and order email.
10. Check ShopBack before you check out. Open ShopBack, tap the store, then check out, so the order costs you less after you pay.

Best online deals: the checks that save the most

The best online deals in the US usually come from three checks: the identical-item comparison, the total delivered price, and the last step before checkout. Those three do most of the work, and the rest stop a good price from turning into a bad buy.

Identical item. Retailers often sell slightly different model numbers of the same product, especially in electronics and appliances. Compare the model number, not the product title.

Total delivered price. Look at the final checkout screen on each site. That is the number to compare, not the price on the product tile.

Return rules. A deal you cannot return is only a deal if you are sure about it. Walmart's Standard Return Policy gives 90 days after purchase or receipt for most Walmart.com items, 30 days for most consumer electronics, and 30 days for items sold and shipped by Marketplace sellers. Most items bought from 1 October to 31 December are returnable until 31 January, with Marketplace seller participation varying.

Shipping promises. Under the FTC's Mail, Internet, or Telephone Order Merchandise Rule, a US seller has to ship within the time it states, or within 30 days if it states no time. If it cannot, it must ask for your consent to the delay, and if you do not agree, cancel and refund.

Best online deals in 2026: when prices usually drop

The biggest sitewide sales in 2026 cluster around Black Friday on Friday 27 November 2026 and Cyber Monday on Monday 30 November 2026, following Thanksgiving on Thursday 26 November. Many US retailers also run large sales around Memorial Day, the Fourth of July and Labor Day.

Window in 2026	Date	What it is usually good for
Thanksgiving	Thursday 26 November	Early-access holiday deals start
Black Friday	Friday 27 November	Often the deepest sitewide cuts of the year
Cyber Monday	Monday 30 November	Online-focused deals, often electronics and fashion
End-of-season clearance	Varies by store, after each season ends	Last season's clothing and home goods

If something you need is not urgent and a big window is close, waiting is often the cheaper move. If you need it now, run the checklist and buy. Our US sale calendar maps which categories usually drop in which month.

Best online deals in the US: Walmart's official price rules

Walmart's own policies are the clearest example of why the checklist matters. According to Walmart's Price Match Policy (updated 8 June 2023), Walmart.com does not match competitors' prices, Marketplace prices, or the price of items you bought earlier on Walmart.com that have since dropped. In Walmart US stores, Walmart will match the price of the identical item on Walmart.com at checkout, with restrictions and exclusions such as special events.

What that means for your checklist:

• On Walmart.com, the price you pay is the price you keep. If you are waiting for a drop, wait before you buy, not after.
• In store, bring the Walmart.com price for the identical item, in stock on Walmart.com at that moment.
• Check who sells it. Walmart-sold items usually have the 90-day window; Marketplace items may have 30.
• Before you check out on Walmart.com, open ShopBack, tap Walmart, then check out.

Temu vs SHEIN: comparing prices on the best online deals

Neither Temu nor SHEIN is cheaper on every item, so compare the same type of item by total delivered price, delivery time and return terms, not by the headline price. SHEIN is built around fashion, with clothing, shoes and accessories at its core. Temu covers a broader mix of home goods, gadgets, crafts and everyday items alongside clothing.

A fair Temu vs SHEIN price comparison in 2026 looks like this:

Check	What to compare	Why it matters
Item match	Fabric, size chart, pack size, product photos and reviews	Similar-looking listings can be quite different items
Delivered price	Item price plus any shipping at your cart size	Free shipping thresholds change the math on small carts
Delivery time	The estimate shown at checkout	Matters if you need it for a date
Returns	Window, return shipping cost and excluded items	Each store sets its own terms; read them on the store's help page
Last step	Start from ShopBack before you pay	Lowers the effective price on whichever store you pick

Both stores update their shipping and return terms over time, so read the current policy on each store's own help page before a large order. Then check ShopBack before you check out on Temu or SHEIN.

Temu, SHEIN and Walmart: where each one fits

Temu, SHEIN and Walmart each suit different shopping lists, and the best online deal often means splitting a list across them.

• SHEIN: trend clothing, accessories and fashion basics when you can wait for delivery. Start from the ShopBack SHEIN page.
• Temu: home, craft, gadget and general items where you want a wide choice at low item prices. Start from the ShopBack Temu page.
• Walmart: everyday essentials, groceries, household goods and branded items when you want a 90-day return window on most Walmart-sold items and the option of a store nearby. Start from the ShopBack Walmart page.

Other stores US shoppers often compare on ShopBack US include Target, Best Buy, AliExpress, Old Navy and Macy's.

Check ShopBack before you check out

Check ShopBack before you check out. It is the final item on the checklist because it changes what the order costs you after you pay. Before you check out, go through ShopBack to get a post-purchase discount on the order.

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles you have to save up and redeem. The number to watch is your effective price: what you paid minus the cash ShopBack returns.

Illustrative example: on a $120 order at an illustrative 5%, $6 comes back as cash, so the effective price is $114. Rates change by store and campaign, so check the live rate on the store's ShopBack page before you pay.

How to do it in under a minute:

1. Build your cart and run the checklist above.
2. Open the ShopBack US app, website or browser extension and go to the store's page.
3. Tap through to the store and check out in the same session.
4. The order shows as pending, then confirms after the store's return window. Our guide on activating before you buy explains why the order has to start from ShopBack.

Can a promo code and ShopBack apply to the same order?

Usually yes, when the code is one the store allows, such as a code listed on the store's ShopBack page or one the store sends you itself. Some stores exclude certain codes or order types, so check the merchant's terms on its ShopBack page before you check out. Our guide to using promo codes with ShopBack covers which code sources are usually safe.

Mistakes that cost you the best online deal

• Comparing the product tile price. Always compare the final checkout total.
• Buying the wrong variant. A cheaper model number can mean an older or smaller version.
• Missing the return window. Mark the last return date when the order arrives.
• Using a random code from a coupon site. Expired or invalid codes waste time; stick to the store's own codes and the ones on its ShopBack page.
• Paying first and remembering ShopBack later. An order usually cannot be added afterwards, so open ShopBack before you check out.

Frequently asked questions

Is there a checklist for buying online to get the best deal?

Yes. Before you pay, check that you are comparing the identical item, who the seller is, the total with shipping and tax, the store's price-match and return rules, the delivery time, whether a sale is coming, which promo code is valid, and which payment method you use. The last check is ShopBack: check ShopBack before you check out so the order costs you less after you pay.

What are the best online deals in 2026?

The best online deals in 2026 are the ones you can confirm on the final checkout screen, not the biggest headline discount. In the US, Black Friday falls on 27 November 2026 and Cyber Monday on 30 November 2026, and many retailers run their deepest sitewide sales around those dates. Outside sale weeks, compare the identical item across two or three stores and start from ShopBack before you check out.

Does Walmart.com give a refund if the price drops after I buy?

No. Walmart's Price Match Policy says Walmart.com does not match prices for items previously purchased on Walmart.com that have since decreased in price, or competitors' prices. In Walmart US stores, Walmart will match the price of the identical item on Walmart.com at checkout, with restrictions.

How long do I have to return an item bought on Walmart.com?

According to Walmart's Standard Return Policy, you have 90 days after purchase or receipt to return most items bought on Walmart.com. Items sold and shipped by a Marketplace seller may be returned within 30 days, and most consumer electronics are returnable within 30 days. Most items bought from 1 October to 31 December are returnable until 31 January.

Which stores give a price adjustment after purchase?

It depends on the store. Target's Price Match Guarantee says you can ask for a match on a qualifying item if Target's own price drops within 14 days of purchase. Walmart.com does not adjust prices after purchase. For Temu, SHEIN and other stores, read the store's own help page before you buy.

Is Temu or SHEIN cheaper for the best online deals?

Neither is cheaper on every item. SHEIN is built around fashion, while Temu covers a wider mix of home goods, gadgets and everyday items alongside clothing. Compare the same type of item by total delivered price, delivery time and return terms, then check ShopBack before you check out on whichever store wins.

How long can an online store take to ship my order?

Under the FTC's Mail, Internet, or Telephone Order Merchandise Rule, a seller must ship within the time it states, or within 30 days if it states no time. If it cannot, it has to ask for your consent to the delay or cancel and refund. Check the stated delivery estimate before you pay.

Can I use a promo code and ShopBack on the same order?

Usually yes, when the code is one the store allows, such as a code listed on the store's ShopBack page or sent by the store itself. Some stores exclude certain codes, so check the merchant's terms on its ShopBack page before you check out.

What does ShopBack do for an online order?

Before you check out, go through ShopBack to get a post-purchase discount on the order. Part of what you paid comes back as cash after the order confirms, so it works like a discount on the price, not like points or miles. Your effective price is what you paid minus that cash. The live rate is on each store's ShopBack page.

When is the best time of year to buy online in the US?

For most categories the deepest sitewide sales cluster around Black Friday (27 November 2026) and Cyber Monday (30 November 2026), with other big windows around Memorial Day, the Fourth of July and Labor Day. Our US sale calendar shows which categories usually drop in which month.
