Restaurant.com takes 80% off all their dining gift certificates via code PRESENT through 6/15. This means that $10 gift certificates, which normally sell on Restaurant.com for $3 are now just $.60 and $25 gift certificates, normally $10 are just $2. This is a great way to save at your favorite restaurant. Obviously, not all restaurants participate, but there is definitely a good selection to choose from. Just be careful to read the fine print as many restaurants exclude alcoholic beverages, weekends and other things.
