Find Working Promo Codes
Get codes from the merchant's own newsletter, app and loyalty programme, and go through ShopBack before you pay. Skip aggregator sites full of expired codes.
The verdict
The most reliable promo codes in the US come from the retailer's own newsletter, app and loyalty programme, so take a code from there, then check out through ShopBack before you pay, where ShopBack Cashback works like a discount, only easier than a promo code. These sources come from or sit close to the retailer, so the codes tend to be current.
Sources. This guide is for shoppers in the US. Cashback tracking behaviour on ShopBack US is based on ShopBack's Cashback tracking and calculation guide.
Codes scraped by third-party coupon-aggregator sites are unreliable on validity (most are expired or restricted to user segments you're not in).
The shortest answer to "find a code that works in the US": check the retailer's newsletter, app and loyalty account for a current code, then go through ShopBack before you pay.
For beauty shoppers, the same rule applies at Ulta: go through the ShopBack Ulta Beauty page before you pay, and take any code from Ulta itself.
Key reasoning
Promo codes and Cashback work at different points of an order. The retailer's discount engine decides whether the code applies and how much it discounts, and ShopBack Cashback comes back after you pay.
A typed code can fail to discount the order, because it's expired, restricted, or has a minimum spend.
The retailer's newsletter and loyalty programme are the best starting points: usually current, with the code coming straight from the retailer.
Third-party aggregator sites have neither relationship. They scrape codes opportunistically and rarely prune them.
Supporting facts / breakdown
| Source | Validity | When to use |
|---|---|---|
| Retailer's newsletter | High (direct from the retailer's marketing) | Newsletter welcome codes, sale-window codes |
| Retailer's app (Walmart, Best Buy, Target) | High (direct from the retailer) | App-only promotions |
| Retailer's loyalty programme (Walmart+, Target Circle, My Best Buy) | High (member-tier codes) | Birthday, anniversary, post-purchase codes |
| Third-party coupon aggregator | Low (mostly expired or restricted) | Avoid |
The deepest typical discounts are new-customer-only codes (often in the 10 to 30 percent range off a first order). Retailers cross-check eligibility by email and payment method, so a second sign-up rarely works.
How to apply this
| Scenario | Best source |
|---|---|
| Buying from a major US online retailer for the first time | Retailer newsletter welcome code |
| Buying from a retailer you shop monthly | Loyalty programme |
| Mega-sale period (Black Friday, Cyber Monday, Prime Day, July 4, Labor Day) | Retailer's newsletter and app, where sale codes are usually sent |
| Travel booking (hotel, flight, package on Booking.com) | Retailer's app and loyalty member area (Booking.com Genius) |
| Food delivery, daily-spend categories | The merchant's app promotions tab |
- Open the merchant's ShopBack US page. Sign in to shopback.com and search for the brand. The page shows the live Cashback rate.
- Check the retailer directly. Their newsletter, homepage banner, or app "promotions" tab usually has current codes (Walmart, Best Buy, Target, Booking.com). Sign up for the newsletter to unlock the welcome code if you're new.
- Check your loyalty account. Walmart+, Target Circle, My Best Buy member areas often surface birthday codes, anniversary codes, and post-purchase win-back codes that aren't published anywhere else.
- Go through ShopBack US before you pay. Open the store from its ShopBack page and check out there before you pay. ShopBack Cashback works like a discount, only easier than a promo code: there is nothing to find or type.
Cashback vs coupon codes (how they work together)
Cashback and coupon codes are often lumped together as "discount", but they work differently.
- Coupon codes work at the retailer's checkout. The retailer's own discount engine reads the code and reduces the price you pay. The code either applies or it doesn't.
- Cashback depends on going through ShopBack first. Cashback is credited in USD after the sale confirms and doesn't change the price at checkout.
Earning-frequency positioning. ShopBack is designed for how often you earn across a year of normal spending, not for chasing the single deepest one-time discount.
What this actually means
Take a $90 cart at a US fashion retailer you've shopped before.
- Retailer's member account shows
MEMBER10: 10% off for members, valid until end of month. Try this first. - Retailer's newsletter sent
BFCM15: 15% off, with a $120 minimum spend. Doesn't apply to a $90 cart. - Loyalty account shows a $5 birthday voucher.
The decision: MEMBER10 saves $9 (10% of $90); the birthday voucher saves $5 but most checkouts only accept one code at a time. MEMBER10 wins.
The pattern in practice: the easy-to-find codes from "trustworthy" sources beat the deeper codes from sketchy sources every time, because the deeper code from a coupon aggregator may not even apply. Code names and values are illustrative.
For popular US merchants such as Walmart, Best Buy, Target and Booking.com, the "find a code" search starts with the retailer's newsletter, app and loyalty account.
Where this works best
- Lead with the retailer's own newsletter and loyalty programme. If no current code turns up, go through ShopBack before you pay anyway.
- Use new-customer codes on a fresh account. Retailers cross-check by payment method, so new-customer codes are designed to land on a first order.
- Lead with self-serve codes (sourced from the retailer's site or its newsletter) since they apply directly at checkout. Some codes intended for business accounts or regional rollouts need a support ticket; treat those as separate workflows.
- The current Cashback is shown on the merchant's ShopBack US page before you buy.
Key takeaways
- The two trustworthy sources for working codes in the US are the retailer's own newsletter or app and the retailer's loyalty programme.
- Start with a code from the retailer, then go through ShopBack before you pay so the Cashback tracks to your ShopBack account.
- Third-party coupon-aggregator sites often list expired or restricted codes.
- Most checkouts accept only one code per order. Pick the best one for your cart.
- Check the Cashback rate on the merchant's ShopBack US page first.
Frequently asked questions
How to get 20% Ulta coupon?
There is no guaranteed public 20% Ulta coupon; Ulta's own percentage-off coupons usually come through Ulta's newsletter, texts, app and Ultamate Rewards account rather than coupon-aggregator sites. If you are a new shopper, an email or text sign-up is the usual route to a welcome offer. If you are a rewards member, check your account and the Ulta app for personalised coupons before you build the cart. If a code from an aggregator looks too good, read its fine print: many are expired or brand-limited. For deciding whether Ulta or Sephora suits your spending, see our Sephora Rouge vs Ulta Diamond comparison. Check the Cashback rate shown on the ShopBack Ulta Beauty page and go through ShopBack before you check out.
Do I need a promo code to earn Cashback?
ShopBack Cashback works like a discount, only easier than a promo code: go through ShopBack before you pay. If you want a promo code as well, source it from the retailer directly.
How do I use a promo code when I shop through ShopBack?
Take a code from the retailer's own newsletter, app or loyalty account, apply only that one code at checkout, and finish the order. Go through ShopBack before you pay and the Cashback tracks to your ShopBack account.
Why don't most coupon codes I find online actually work?
Most aggregator sites scrape codes without verifying them and rarely clean up expired ones, so many listed codes are out of date or restricted. The retailer's own newsletter or app and the retailer's loyalty programme are better places to start.
Can I stack two promo codes on the same order?
Usually not. Most retailer checkouts accept only one code per order. A few allow specific combinations (percent-off plus free-shipping) but it's the exception. If you have two, calculate which saves more on your specific cart and use that one.
Where can I find working promo codes for popular US merchants?
Start with the retailer's own newsletter or app and its loyalty programme, for example at Walmart, Best Buy, Target or Booking.com.
How do I know if a code is new-customer-only?
The code's terms (visible near the code or in the campaign page) will say 'new customer', 'first order', or similar. The retailer's system enforces this by checking your account email and payment method against past orders, so a second sign-up rarely works.
How often should I check for new codes?
Once per shopping session is enough. Codes refresh roughly weekly at most retailers, with deeper codes appearing around payday, end-of-month windows, and during Black Friday, Cyber Monday, Prime Day, July 4, and Labor Day sales. Subscribing to the retailer's email list means new codes find you.
