One of the most comprehensive, as well as the only one I have personally used. It’s usefulness also stems from its popularity, as there are many ratings and comments next to each code.

Fatwallet, strictly speaking, is a rebate site. It is an “associate” of various retail stores and, as such, it receives a rebate. It then shares this rebate with its customers. The main reason people access this site, however, is the forum discussions. Many of the users are ardent deal finders and have very good tips.

A good site for deals with a twist: You will find one very good deal featured on this site each day. The product may run out quickly, and it till definitely be gone in 24 hours, but if it has what you want it’s a great bargain. Enjoy.

Similar to Woot.com in that you will find one very good deal featured on this site each day. Once again, the product may run out quickly (Yugster stands for ‘Yours Until Gone’ - ster), but if it has what you want it’s a great bargain. Enjoy.

Coupon Cabin. Search powered by Cheapuncle.com, although this seems to be a better starting site as it features up-to-date new codes.

The one I would recommend least. Just a preliminary search makes me think these are more ads than coupons. I may be proved wrong, however.

http://currentcodes.com/
Seems quite up-to-date. Selection might not be as big, as there isn’t even a search function. Rather you choose stores and find coupons under each one that is featured.

http://www.couponalbum.com/
Coupons handily categorized under New, Free Shipping, Printable, etc. Also a search section and a section on just plain Good deals (appropriately called Deals).

Thanks to Meeyong for bringing this to our attention. I haven’t tried it yet, but it is a list of many different retail deals; from online coupons to $100 giftcards for test driving a Lexus. If you have had any experience with this site please let us know.

A very no-frills website featuring coupons, a forum, and new deals in general. Here again, if anyone has tried this please comment and let us know.

Brad asked us to add this site to our list, so we have just started using it. It is easily searchable (although not all the brands listed have coupons), and the Top deals really are good deals. We will let you know more as we use the site more. But we do know that he was interviewed on MSNBC.

This site asks you to sign up (it asks for your home address as well, but you do not need to fill that part out at first). Once you are signed up, however, it offers certain deals not available to the general public (for ebates members). Again, this site is new to us. If any of you has any experience with this please let us know!
