If you're on the hunt for a mega discount, Subway has announced a huge deal.

The fast food giant is offering customers buy one get one free on Footlong Subs when they order through the new app.

In order to qualify, guests simply need to download the new Subway Official app, which is free on the App Store and Google Play.

The offer, which is valid until November 1, is only available when ordering through the app for collection in participating stores.

Although limited to a Footlong Sub per order, the promotion isn't a one time only offer.

Subway Rewards customers can order as many times as they want until Sunday.
