One of the best deals I've found recently is at Restaurant.com, which was advertised in the CouponMom.com newsletter.
I happened to get that newsletter the morning of a dinner date with Granny and Granddaddy at one of the restaurants featured on Restaurant.com. It sounded too good to be true, but I figured it was worth a $5 gamble. I typed in my ZIP code, chose from the participating restaurants (there are only TWO in our area), paid online and printed the gift certificate.
And it worked! Thanks to Restaurant.com plus an additional 50-percent-off code from CouponMom.com, we paid $5 for a $25 gift certificate.
It's definitely worth investigating for anyone who likes to eat out. These cheap certificates also would make great Christmas presents. For the most savings, use the code THANKS through Nov. 30. But even without a special code most of the certificates cost $10 and are worth $25.
(FYI: I paid for the first certificate through PayPal and it went through with no problem. But the next time I tried to use PayPal to buy one it didn't work -- it charged my account but wouldn't let me print the certificate. I called Restaurant.com and got it straightened out within about two minutes, but they said they'd been having some problems with PayPal, so in the future I'll probably just pay with my credit card.)
