Restaurant.com is offering $25 gift certificates for $2 again when you use code FUN! This is a good way to try local places. Just put in your zip code and see what places are participating.
If you go through Ebates first you'll also get 20% back plus $10 if your new!! Um...that's a pretty good deal.
Most certificates from Restaurant.com come with restrictions so make sure to read them before you buy. Commonly it's you have to spend a certain amount to use it and it's dine in only. Also most I've seen have at least a year expiration date, if they have one at all.
If your using Ebates for the first time:
