The frequency and timing of Subway's sandwich specials vary, but many specials change monthly. Subway also occasionally offers deals on special days, such as National Sandwich Day. Since Subway is a franchise, owners have some control over what specials their restaurants offer.
Subway's $5 foot-long promotion, which is optional for franchises as of 2015, features certain foot-long sandwiches for $5 every month. One or more featured sandwiches, which change every month, are also available for $5.
Subway offers both short-term and long-term specials. Its Simple $6 menu, which includes a 6-inch sandwich, drink and bag of chips for $6, has run for over a year. Other specials, such as a $2 6-inch sub special and a buy-one-get-one free special, were only available for a month and a day, respectively.
