Restaurant.com is offering 80% off when you use the code JOY at checkout! There are a few rules that apply to these deals, but they are worth it if it's a restaurant that you like to eat at or would like to try. You usually have to spend $35 (not including alcohol) for a $25 certificate, but then just hand over the $25 certificate (that you purchased for only $2!) when you are paying and they'll deduct it from your bill. We've enjoyed WOW Cafe and Wingery and and our local Eggspectations for the same price we would pay at a fast food chain.
If you purchase the certificates through Ebates you'll get 15% cash back! Just head over to Ebates, search for Restaurant.com and purchase your dining certificates. Make sure you use code JOY at checkout to receive the 80% off discount!
