Ever since the first web shops opened there were coupons.  Every site wanted to attract customers so they gave out great coupons for first time visitors and since then the web has had many forums and websites filled with coupon codes that never work and infuriate bargain hunters. Yahoo! Deals just started recently, but I don’t think it is quite up to the par developed by other sites, particularly in the area of coupons.

Yahoo! Deals indicates when a coupon expires, but not it’s success rate. The expiration date may be incorrect or the coupon may not work for many people for various reasons. They offer a simple vote up or down option but no clear indicator of success.

RetailMeNot on the other hand has a great interface that provides a clear indicator of success in a visual format over time as seen by the green/red chart, and then they have a nice slider at the top that allows you to exclude coupons that fall below a certain success rate.

I do appreciate that both have the ability for users to interact without being signed in or created an account.

Yahoo! Deals does have other nice features but this particular area for coupons is lacking and RetailMeNot has clearly provided a much nicer user interaction.
