We recently wrote about a phenomenal deal at Restaurant.com that let you purchase a $25 gift certificate at a participating restaurant for just $5. It was like getting handed a $20 bill. We told you. We told our friends. We told our friends to tell their friends. Deals like this don't roll around too often, we said. But (yay!) we were wrong.

Now Restaurant.com has put an even more unbelievable deal on the table. If you buy a $25 gift certificate by 3pm EST on Monday, January 19, you'll only pay $4. That's a quick $21 saved with the click of a mouse.

What's great about Restaurant.com is that it includes a good selection of eateries from all over—not just big cities, though they are well represented, too. This is a great opportunity to grab a cheap meal out in your own hometown. (These coupons make great teachers' gifts, too.) But think ahead, also, to your future travel plans so you can save on a meal at a nice restaurant (or two! or five!) in your next destination. To take advantage of the $4 offer, use the promo code EXCLUSIVE at checkout and hit the "apply" button.
