Subway is offering several of its foot-long sandwiches for $5 during the month of September for its “SUBtember” promotion.

Ads featuring the “$5 Footlong” jingle advertise the sandwich chain’s monthlong deal with appearances from Subway spokespeople like Olympic swimmer Michael Phelps, pro footballers Justin Tuck and Robert Griffin III, and boxer Mike Lee.

Subway’s website lists up to 21 sandwiches that are available as a $5 Footlong this month, including breakfast sandwiches. Participation and prices may vary by location, according to the company.
