As of June 2015, Subway.com does not have any announcements regarding online coupons. However, the coupons websites Offers.com, Coupons.com and RetailMeNot.com list Subway coupons and promos that users have shared.
The Subway website encourages customers sign up for email updates for a chance to win a year's supply of foot-long sandwiches. The coupons posted on third-party websites cover in-store, catering, online and student discounts.
Some customers claim that when they tried to avail of these promos, they were still asked to present the printed coupons that came from local newspapers. The website users also reminded others that these promotions are only available from participating Subway stores.
