RetailMeNot.com - coupon codes for online stores
"Many online stores allow for a "coupon" or "promotion" code when you order to automatically assign discounts, deals and freebies (kinda like money for nothing). RetailMeNot.com is a place for finding and sharing these coupon codes.
So... when you buy online, check here for discounts first (unless you're frikkin crazy)."
