On some big events such as Black Friday, Valentine's Day,... b2s will constantly offer up to 50% discount or more, so all customers can purchase well on their budget without worry.

Discount codes don't stack. If you have 54% off discount, they can't also use a "free shipping" coupon since Only one discount at a time can apply to a single order at the b2s site.

Usually, Coupon Stacking is not allowed at b2s. However, the store will surely give out notice if available.

Let us know via email, our team will confirm with b2s to fix and remove all Promo Codes, Coupon Codes, and Deals that aren't working.
