It’s hard to know when this deal is on and when it’s not. But my Jack’s is still advertising it on their sign. This may be a “vary by location” deal.
Milkshakes at Jack’s are Buy One Get One FREE from 2:00-5:00pm every day!
Plus, be sure to join the Jack’s Red Dot Club for more savings! (I had three coupons in my email this morning from Jack’s Red Dot Club!)
