Restaurant.com certificates used to be a great way to save money. Sure, you must read the fine print. A minimum purchase is required and many have specific days that are blacked out. It has saved me some money, however I have had several certificates refused at the restaurant. They've just decided to no longer except for various reasons, apparently there is a fraud problem with these certificates, so it's hard to fault the restaurant. Restaurant.com says you can exchange an unused certificate for another, but it's a huge hassle. I don't know the solution, I'm just saying BE CAUTIOUS. Read the fine print and don't let certificates get close to expiration (1 year from purchase) so you'll have time to exchange if refused. Because the customer service at R.com is like most companies and pretty much non-existent.
