From Dec. 16 to 24, 2024, Smashburger is offering a buy-one-get-one FREE burger or sandwich at participating locations. The offer is only available in restaurant.
Use promo code 4031 at checkout to redeem the offer in-restaurant. For a list of participating locations, click here.
For each burger or sandwich purchased in a transaction, get any burger or sandwich for FREE on the menu of equal or lesser value to the item purchased. (Protein substitutions available.)
No limit on number of qualifying complimentary items that may be redeemed in a single transaction. That means you can use the offer multiple times in a single transaction — just be sure you’re ordering burgers and sandwiches in multiples of two.
This deal is from Living on the Cheap, our sister site.
