Potbelly Sandwich Shop offers fans an escape from the PSL onslaught by offering a PSF – Potbelly Shake for Free from September 20 through September 23, 2019.
In order to take advantage of the offer, simply stop by your local participating Potbelly Sandwich Shop during the promotion period and you’ll be offered free shake with purchase of any entree.
Potbelly’s hand-scooped shakes come in a wide range of flavors like Cold Brew Coffee, Oreo Cookie Banana Split, and Mixed Berry, all topped with whipped cream, a cherry, and a butter cookie on the straw. And they also come with the Potbelly guarantee – absolutely none of them are pumpkin spice flavored.
