Restaurant.com has a coupon code (MENU) which gives you 80% off its already-discounted prices on restaurant gift cards. Previously, a $10 gift card would cost $3, but with the coupon code, it's $0.60.
Each participating restaurant has restrictions for the gift certificate use -- no such thing as a free lunch, after all -- so check what you're committing to before you purchase. For example, it looks like most $10 gift cards are valid on a food purchase of $25 plus gratuity, so spending some money is unavoidable. The more draconian restrictions exclude drinks. Still, this basically amounts to free $10 or $25 gift cards to places I'd be eating at anyway.
After purchasing the gift cards, I was able to print them right away, with no wait for shipping. We're looking forward to putting these to use.
