Through December 25, promo code Santa is good for 80% off purchases from Restaurant.com. A standard e-certificate costs $10, so this code makes it $2.

Now, I don’t really use these certificates. But Restaurant.com is a frequent shopping partner valid for various promotions. And for the US Airways Holiday Shopping 250% mileage bonus, you can purchase Restaurant.com certificates through ThanksAgain to earn a partner. And of course you need 5 total partners in order to reach the 250% earning threshold. So here’s a $2 option.
