i am a huge fan of restaurant.com
and i was shocked to find that many people do not know anything about it.
basically you can get gift certificates for incredibly cheap.
usually $25 GC for $10.

BUT... i NEVER pay that price.

usually i get $25GC for $2 OR $10GC for .60cents!

yes you read that correctly. i usually just find codes online to make them that cheap.
if you go buy some now use the code NAPKINS to get that price (the super cheap one) above.

and, i DO use these. and they ALWAYS work. i also used to receive them when i worked in a restaurant and i never, ever had a problem redeeming one that my customers gave me.
