Chrome/Firefox/Safari/IE: We've always loved coupon sites like RetailMeNot for finding discounts at a moment's notice, but Coupon Follow decided to take it a step further by integrating their coupon data into the checkout process. Their extension, Coupons at Checkout, suggests available discounts and promo codes on available online store pages so you don't even have to look them up.


All you have to do is install the extension and visit a supported online store (e.g. Target, Amazon, DELL, CVS, Macy's, Domino's Pizza, Travelocity, and many more). When you get to the checkout page, find the section for coupons or promo codes and click on it to make your options appear. In my tests, sometimes I had to click on the text field, click outside of it, and click on it again to get the list to appear. Nonetheless, several results were provided in order of usefulness.

Coupons at Checkout is a free extension and runs hidden in the background. You'll only see it at checkout, which is exactly when you'll want it.


Update: I made a mistake—Coupons at Checkout supports Firefox, IE, and Safari in addition to Chrome.
