I'm not promoting Ebates, but I think everyone needs a little cash back when you shop online.  Cash back everyday, and double cash back during special days and holidays.  No silly spamming, membership fees, and all those nonsense gimmicks. 

1. Ebates.com 
2. Select an online store.
3. Make a purchase. 
4. Cash back tracked. 
5. Ebates mailed or direct deposit the check.

Here's me making a recent Black Friday week purchase of 2 computers.  One my brother wanted to purchase for himself, and one for myself after my previous computer died few months ago. :(
