Discount codes don't stack. If you have 57% 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 Cosmos site.

Of course not, most coupons may be used only by you when you received them directly from Cosmos. As the Cosmos coupon includes your User ID, it cannot be resold or transferred in any way.

To avoid this problem, you should check out carefully Cosmos promo code before that promo code could be expired, some promo codes are tied to a minimum purchase, a first-time purchase, or tied to geography, and other reasons.

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

There are now 18S offers on our site and Cosmos Coupon Codes usually end in 3-4 days. However, some Cosmos Deals don't have a definite end date, so it's possible that the code will be working until the store runs out of inventory for the promotional item.

The sitewide discount from Cosmos is applied on certain purchases. For Year-End Deals, the store may have its own requirement to offer you a sitewide discount.
