What TopCashback does on your store

Where does it get your codes?

TopCashback's US terms say the codes on its site are posted either by TopCashback or by its members, and that it can't be held responsible for whether they work.[TopCashback USA, Oct 2026] (opens the source) The UK Safari extension notifies shoppers when it finds a voucher code and can apply it to the basket automatically.[Apple App Store, Oct 2026] (opens the source)

What does it do in a shopper's session?

TopCashback publishes no stand-down policy, and its help centre tells members to log out of other cashback or coupon extensions so they don't override its click.[TopCashback UK, Oct 2026] (opens the source) Its Group Commercial Director, James Little, co-wrote a proposed code of conduct for affiliates that use browser extensions with Benjamin Edelman, published for comment in April 2026.[Benjamin Edelman, Apr 2026] (opens the source) That code is a proposal, not a rule TopCashback is bound by.

What does it cost you?

Every order where it applies a code gives away the discount, and the shopper was usually already at your checkout with a full basket. If it's in your affiliate program, the same order can also pay it commission under last-click attribution, on top of the discount, whoever actually brought the shopper.

So the cost is the discount plus any commission on orders that would have happened anyway, and the codes it spreads keep working until you replace them.
