Usually, you can enter the discount code during checkout. However, if you do not meet the following conditions, you may encounter some errors:

1. Not reached the Minimum purchase amount or Minimum quantity of items.

2. Some coupons are bound to the customer account, and cannot be shared with others. Please contact customer service if you need assistance.

3. Some codes are designed for specific products.

4. Coupon codes don't stack. If you have a 10% off discount, they can't also use a "free shipping" coupon. Only one discount at a time can apply to a single order. (Resolution: Use the higher discount code on your order. )
