Q
Why did the total price become higher after using coupons?
Answer Question
A
Here are some reasons that may cause this:

1. Coupons cannot be used on promotional products;
2. The price after coupon is converted based on the original price but not the promotion price when using a coupon.

If the item is on promotion, we kindly suggest you compare the price after using a coupon with the promotion price, and you could click "remove discount" when it is more expensive than the promotion price.
