Ran across something very cool the other day. It is called Ev'reward and it is a search engine/directory of online shopping rewards. The directory includes over 14,000 rewards for over 3,000 online stores, available through more than 40 leading cash back, frequent traveler, savings reward and points programs.

How it works:

1. Go to Ev'reward
2. Type in the name of an online store
3. Ev'reward will list online savings programs that include that store and the rewards associated with them

It also has a "Browse" function, so you can look at all stores in a particular category.

Although it does not have every possible rewards program (Bank of America Add It Up and Grobux, for instance are not available through Ev'reward) it has a lot. If you are signed up with multiple reward programs, Ev'reward is a huge timesaver!
