I don't know many people that don't like pancakes...so this freebie is a no brainer - especially since you get a meal for free, not once, not twice, but three times for becoming a member of the Pancake Revolution.
All you have to do to join the IHOP Pancake Revolution is to go the the IHOP site or sign up via the IHOP Facebook. Once you sign up you will get an email for a free Rooty Tooty (or another option for up to the same price). Then again they'll send you another freebie on your birthday AND, if they weren't generous enough, another one on your one-year Pancake Revolution anniversary.
You also can sign up your whole family and get the same thing - so...what are you waiting for?
And remember, your meal is on me this time!
