Through 7/19, use code VACATION at Restaurant.com to take 60% off dining certificates. This means that $10 gift certificates which normally sell for $4 are now just $1.60 and $25 gift certificates, normally $10, are now just $4. As an added bonus, the code will also get you a free $50 Orbitz.com coupon code. The code can be used towards a 4-night vacation package for travel before 9/10. Not all restaurants participate, but there is a good selection to choose from. Just be sure to read the fine print, as many places exclude alcoholic beverages, weekends and other things.
