Denny's Offering Free Grand Slam Breakfast

A Free Grand Slam breakfast from Denny's sounds great to me.  Just don't tell my doctor...hehe.  As with all good things, there IS a catch.  Apparently they want you to order online.  If you sign up with Denny's On Demand, you get one free breakfast.  The promotion goes through January 31st.  For more info, Click here
