SAN DIEGO — Subway is celebrating National Sandwich Day by offering a promotion to its customers.
The sandwich chain is holding a “Buy One, Give One” offer Tuesday at participating locations.
Customers can buy any sub and a 30 oz. drink and get a free sub to share with anyone you choose.
The free sandwich must be of equal or lesser value.
Subway says that while they do encourage all stores to participate in the promotions, it is always best to check with the individual franchise.
