Jack in the Box is offering one free 5 piece churros per coupon, per visit. Expires 12/31/2020. Hopefully I didn't miss this posted somewhere else but thought to post as my kids, wife and I are addicted to them and we were able to stop at 3 Jack in the Boxes all in close vicinity for a grand total of 60 churros.
One thing to note is that each location had issues inputting the coupon code and the manager had to manually mark it as free. Not quite sure what the issue is. Possible that their pos system hasn't been updated yet to accept the code.
*Update 11/18/20: Their systems are finally updated to accept the coupon code and confirmed at multiple locations without any issues.
