On April 21, Jimmy John’s is running a Customer Appreciation Day promotion that will see the sandwich chain offering $1 subs for a limited time during the day.

The $1 sub offer will be available from 11 a.m. until 3 p.m. at participating Jimmy John’s locations nationwide. The deal applies to the chain’s Slim line of 6 sandwiches, including Ham and Cheese, Roast Beef, Tuna Salad, Turkey Breast, Salami Capicola Cheese, and the Double Provolone.

All $1 subs come on Jimmy John’s French bread. If you’re trying to curb carbs, the JJ Unwich lettuce wrap will be available at no additional charge. If you would like to get a sandwich on JJ’s 9-grain wheat bread there may be an additional fee depending on the location.

The Customer Appreciation Day promotion is available on in-store purchases only and there’s a limit of 1 sub per person. If you would like more than one $1 sub you can go through the line as many times as you like or invite your whole group to the store.
