Why some coupon codes stop working sooner than the expiry date says

An expiry date is the last day a code can work — not a promise that it will.
A coupon code has two lives. There is the date the store publishes, and there is the moment the store quietly switches it off. The second one comes first more often than you would think, and understanding why saves a lot of frustration.
Usage caps are the most common reason. Many codes are issued with a limit: the first thousand orders, or the first five hundred customers. When the cap is reached, the code dies regardless of the printed date. This is especially common with codes tied to a launch or a single product.
Budget exhaustion works the same way. A store sets aside a sum for a campaign, and when the discounts given away reach that sum, the campaign ends early. You will rarely see this announced.
Regional restrictions catch people out constantly. A code that works perfectly on a store's German site may be rejected on the same brand's Austrian or Swiss site, because they are separate shops with separate systems. If a brand operates several country stores, check you are on the right one.
Account-level limits apply per person, not per code. "One use per customer" means that if you or anyone in your household used it before, it will not work again, even though it is still live for everyone else.
Stacking rules end quietly. Some codes stop working the moment a sale starts, because the store doesn't want the discount applied on top of already reduced prices. The code isn't expired, it's just excluded for the duration of the sale.
What this means in practice: treat the expiry date as the outer boundary, not a guarantee. Newer codes are more likely to work than older ones, which is why we sort them that way. And if a code fails, don't assume the whole page is stale — try the next one down, because it may have been added yesterday.
We remove expired codes automatically, so nothing on the site is past its date. What we cannot see from outside is when a store hits its own cap. That is where reporting a broken code genuinely helps: one report from you can clear a dead code for everyone else.
