I love the Birthday e-Clubs that restaurants offer.
Here are 3 restaurants that will give you a FREE burger on your Birthday
Follow the links to sign up
These usually send you coupons and freebies throughout the year.
On a side note, I know that I send you to alot of places that require you to sign up with your email address, and I know how annoying it is to have 500 junk emails to have to sort through.
I would suggest to you creating a separate email account for these offers, I have 3 Gmail accounts and one is just for the things I don't really care to deal with, another is for the email updates I am truly interested in and then my personal email. It really helps to keep it all organized...just a thought :)
