How to use a coupon?
If you have valid coupons, you may select one or input the coupon code on Shopping Cart page before checkout. Once you click Place Order, it means the coupon will be used.
a) The coupon won’t be returned once it’s used, even if you cancel the order or apply for a refund.
b) If you return any of the items purchased with a coupon, the coupon discount or value will be subtracted from the return credit.
Why can't I use my coupons?
The possible reasons you can’t use the coupons:
1. The coupon you choose has expired.
2. The coupon code you input is incorrect.
3. Your order doesn’t qualify for using coupons, such as, your order doesn’t meet the required minimum amount, or the coupon is only available for certain products, and etc.
