Subway is a customer favorite, in part because they always offers deals and discounts. Not to mention, they can be a healthy alternative to fast-food. They’re now offering a dinner deal — every day after 4 p.m., and all day Sunday, you can get a Footlong Sub for $5. However, you must buy two or more to get the promo price. The sale sandwich excludes Premium and Supreme subs. The offer is for a limited time and valid at participating locations.
