It happens all too often: You make a beautiful (not sad) lunch to bring to the office…only to forget it on your way out the door.

Dry your eyes, though, because Potbelly Sandwich Shop is giving away free sandwiches all through the month of October. All you have to do is download their mobile app and register as a new user. You’ll automatically get a coupon for one free sammie. (Dibs on the pizza one.)

The only caveat? The offer ends after October 30…or when the 75,000 free sandwiches run out. Quick, grab your phone.
