To use the Amazon coupons on their website, you need to meet the conditions:

•  The items you choose must meet all coupon requirements as explained in the Terms and Conditions.

• The coupon has not expired. 

• The seller uses the Amazon checkout system or a customized checkout system that accepts the coupon.

To avoid this problem, you should check out carefully Amazon 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.

There are now 36S offers on our site and Amazon Coupon Codes usually end in 3-4 days. However, some Amazon 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.

Shoppers can get coupons for their first purchase at the store. However, it is not all the time, sometimes, they cannot apply a discount on items selling out or items not contained in the promotion program. It depends on the time you shop at Amazon.

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

It is hard to see a Sitewide Discount of 50% from Amazon on normal days. It's easier for you to shop on federal holidays or important days of the year. New Year’s Day, Thanksgiving, Christmas, Military Day...are recommended.
