I bought restaurant gift certificates from restaurant.com but merchant wouldn't accept it. Apparently restaurant.com just wrote up a "deal" without the merchant's permission! Merchant spent hours getting restaurant.com to take her restaurant off their list. DO NOT BUY ANYTHING FROM RESTAURANT.COM. Shame on them. Fortunately my credit card company refunded my purchase upon dispute.
Tip for consumers: DON'T EVERY BUY FROM RESTAURANT.COM - IT'S A SCAM!
