Abstract: A system and computer program product for testing the validity of coupon codes. Coupon codes can be automatically tested, instead of manually testing them, by having a program select one or more products on a merchant's website and then add them to the shopping cart on the merchant's website. Upon entering the checkout stage on the merchant's website, the program can submit the coupon code to be tested at the checkout stage. The validity of the coupon code is determined based on the status of the coupon code (e.g., expired, approved advertised benefit) returned by the merchant's website. By having a program automatically test coupon codes instead of having a user manually test each coupon code, the validity of coupons code can be more accurately determined in a more efficient manner.
