It’s Potbelly’s 40th birthday and they’re celebrating by giving us 40% off one of their original sandwiches. The catch? You have to mention their birthday while you’re there!

Our bday is June 1st, and for our 40th we want to #FeedYourSmile. Come celebrate and get 40% off Originals sandwiches on 6/1 from 11am-3pm. pic.twitter.com/2LPH2Ky5rY
