   Start with the store itself, then use coupon sites only as a lead to test at checkout. Most of the guides I found say the same thing: a code is not confirmed until it changes your cart total.

   1. Check the retailer first. Look at the homepage banner, the sale or clearance pages, your account or app, and the email signup offer. Starting with the retailer makes more sense than copying the first code you see in a search result. Account-based offers sometimes appear only after you sign in.

   2. Use coupon directories carefully. Sites that list codes by store can save time. A legitimate coupon should clearly state which retailer it applies to, what it discounts, when it expires, and any minimum purchase. A listing with a recent check date helps, but a date is not proof that the code still works.

   3. Consider browser extensions as an extra check. Extensions can try saved codes automatically at checkout. They should be treated as an additional check rather than a substitute for reading terms. Install only well-known ones and review what permissions they request.

   4. Look for cashback or rewards stacking. Cashback portals and card-linked rewards can add savings on top of a code. Review activation requirements and tracking rules before ordering.

   5. Test at checkout, one code at a time. Add the items you plan to buy, enter one code, and confirm that the discount appears as a separate line. Check the actual amount removed from the subtotal and review whether shipping, taxes, or other charges changed. If a code fails, read the error message rather than trying a long list of codes.

   6. Watch for red flags. Be cautious of any page asking for a credit card number or other sensitive information just to reveal a code. Also be cautious of codes that require you to hand over personal details or complete a survey first.

   7. Compare the final total, not the headline percentage. A free-shipping code can be worth more than a bigger percentage off on a small order. Also check whether a code replaces a sale price you already have.

   If you tell me which store you're shopping at, I can search for its current promotions and check whether any recent codes have been reported as working or expired.
