walk in to a jack n da box on tuesday november 16th and get two free tacos. I imagine you can't have more than 1 visit a that day. I just saw a commercial about it. http://dealitem.com/Deal/2354516/TAC...S-TUESDAY.aspx
I haven't had their taco's in years. When I lived in Houston years ago one was close and I used to eat them all the time. They are really good. The only hard shell that don't break as you eat it.
