I have used rest.com gift cards and it's awesome. seems too good to be true I know! only thing to watch for is some areas only have a few participating stores, we had to wait for our zip code to add places we liked, and some gift cards are for like "must buy 2 entrees" "not valid on weekends" etc. other than that it's really worth it, and they tell you the stipulations up front.
