Click here to register for the Quiznos club. You should recieve coupons and promotions via email. This says you will get a free cookie on your birthday and a free sandwich with registration. I signed up this morning and will let you know if I get my coupon!
EDITED: I got my confirmation email right away and when you click to verify the email address it gives you a printable coupon for a free sammie when you buy chips and a drink. Not as good as I originally thought but still a pretty cheap lunch!
