There are sure a lot of restaurants that have been giving away free meals lately! From Denny's to IHOP to Jack in the Box, and now Quizno's. I have not posted a lot of these deals since they are usually only one day, and many people would log onto this blog too late.
However, you can get a coupon for a free sub from Quizno's just by visiting this site.
You do have to enter a valid email address. If this deters you, you may want to consider forming an email address just for deals like this. I have one that I use for any company that asks for my email (and a separate personal one).
Enjoy your sub!
