$6 Burgers at Smashburgers Through December 21, 2023

Smashburger offers a short-run deal where you can get Single burgers for $6 each at participating locations across the US through Thursday, December 21, 2023.

You can redeem the special by using the code "GIFT23" through the Smashburger mobile app or website.

The discount is good for any Single version of any burger build on the menu except for those with chicken or brisket (which means you can go with beef, turkey, or black bean patties). There's no limit on how many discounted burgers you can order.

Most of the chain's Single burgers normally cost $10.99 a piece at the nearest Smashburger restaurant for me.
