(WENY) -- Subway restaurants are giving away up to a million six-inch subs on Tuesday to showcase their new deli sliced meats.

To get a free sub, customers will need to physically go to a participating location between 10 a.m. and 12 p.m. and choose a six-inch sub from their new Deli Heroes Lineup menu. Only one free sandwich is allowed per person, and restaurants won't take any other coupons. 

The company invested more than $80 million in new deli meat slicers for 20,000 Subway restaurants, and is doing the promotion to show off the new products.
