With the dog days of summer over, Potbelly fans can welcome the back-to-school season with a buy one, get one sandwich deal.

On Tuesday, August 27, Potbelly is offering fans a free Original-sized sandwich when they order an Original or Big Sandwich using the promo code ‘BOGO’ through Potbelly.com or the Potbelly app.

“As summer winds down and back-to-school routines ramp up, we wanted to give our customer’s wallets an additional break during this busy season,” said David Daniels, Chief Marketing Officer at Potbelly. “Our Back-to-School BOGO is here to make the transition a little tastier whether you’re a student, a teacher, parent or just a fan of our craveable oven-toasted sandwiches. “
