You can cool down with a free shake deal available at Potbelly Sandwich Shop this week.
Potbelly is calling the new promotion "Free Shake Friday," and all customers can get the free shake on Friday, June 29. All you need to do is order any sandwich or other entrée at Potbelly on Friday and say "shake it up," and you'll get a free shake in any flavor you like.
It's easy to get a free Potbelly shake one day before the masses, though. All members of the Potbelly Perks loyalty program will get a free shake offer on the app that's valid on Thursday, June 28. (The purchase of an entrée is required on Thursday as well, in order to get your free Potbelly shake.)
The Potbelly rewards program is free and easy to join: Just submit an email address and download the app. In addition to scoring a free shake on Thursday, Potbelly Perks members can get sweet deals like free food and drink on their birthdays.
And hey, there's nothing to stop you from getting a free shake for Potbelly Perks members only on Thursday, and then following up by taking advantage of the free shake deal for the masses on Friday.
