Check out this 80% off discount for Restaurant.com, good today through Thursday, June 24, 2010. Use coupon code SUMMER. With the same code, you can also get 80% off dinner of the month club. The coupon code makes each $25 certificate, which normally sells for $10, just $2 a pop.

Before you buy, read the redemption rules because they vary by restaurant. Most will require you to rack up a food bill above and beyond the certificate, say $40 or $50 for a $25 cert. Virtually all will exclude alcohol, tax, and tip. Some may specify which days and times the certs can be used. In general, you can only use one certificate per table. I've crunched the numbers, and these certs end up saving you 20-40% off your bill. Not too shabby!
