If you haven't signed up for Groupon do it now. It's totally free and wonderful. Basically, you can either get emails or just go to the site (after signing up) and get great deals, discounts and coupons. Today I got a great one for Red Robins. The deal was this: for $10 you can get a $20 gift card. No need to wait for it in the mail. After you buy it, you can print it up right then and there. If you print it and misplace it, no problem, you can print it again, but remember you can only use it once. If you buy more than one, you'll have two different certificates to print.
Here's the link to sign up:
