This deal has ended.
Update: the code has been extended through 10/1! Use code WOW at Restaurant.com to take 90% off dining certificates. This means that $10 gift certificates which normally sell for $4 are now just $0.40 and $25 gift certificates, normally $10, are now just $1. This matches the lowest discount we have ever seen for them. The discount is valid on all restaurant dining certificates but excludes Restaurant.com gift cards. 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. Due to overwhelming traffic, the Restaurant.com site is running a bit slow.
