Thanks very much to my friend, E. who alerted me to this very cool site! http://www.ebates.com
I have yet to use it, but basically, if you purchase products from all kinds of major stores through this site, they will send you a cash rebate in the mail for a percentage of the purchase price. You can also find and use coupon codes here in addition to your cash back rebate. Some stores that are included are:
Barnes and Noble
The Disney Store
The Children's Place
and many more!
