Apply, Apply best, and the honest result line
When you click Apply, AliCheckout types the code into AliExpress' own promo field and presses AliExpress' own Apply button. That is the whole mechanism. There is no interception of prices, no modification of the order total, no request sent to any server of ours. AliExpress validates the code exactly as it would if you had typed it, and AliExpress decides whether to accept it.
Apply best looks at the rows that are valid for your current total, picks the one with the largest discount, and applies it. If you have several codes for the same store, this saves you from having to compare them yourself.
After the click, the panel reports the real outcome rather than a hopeful guess. These are the messages you can see:
- Applied · you save €0.96The code was accepted by AliExpress and the order total has been reduced by the amount shown.
- AliExpress' own messageIf AliExpress rejects the code – for example because the order is below the minimum, or the code has expired since collection – the panel shows AliExpress' exact response, not a paraphrase.
- Already appliedThe code you clicked is already active on this order, so nothing changed.
- AliExpress kept your current coupon (−€3.01) – it saves more. Only one store coupon applies per order.AliExpress allows a single store coupon or code per store per order. If the one already on your order is better than the one you tried, AliExpress keeps the better one and AliCheckout tells you so instead of pretending something happened.
