Subway stores and concessions will be offering a ‘buy one, get one free’ promotion on Valentine’s Day.

The vast majority of sites, including concessions within convenience stores, are participating in the Customer Appreciation Day offer, which will give customers the opportunity to buy one Six-inch Sub of their choice and receive another Six-inch Sub completely free.

Customers just need to head into stores between the hours of 11am and 7pm and place their order.

In addition, customers who take up the offer will receive a voucher giving them another month to claim two separate offers. Available to redeem from 15 February-15 March 2018, the voucher enables purchase of a Six-inch Mega Melt Breakfast Sub for the discounted price of £1.50, as well as a free upgrade to a Footlong when buying any Six-inch Sub or flatbread.

The offer will be supported with a social media campaign to spread the word about the brand’s ’buy one, get one free’ deal, and to encourage customers to #shareyoursub.

SubwayUK and Ireland marketing director Sacha Clark said: “We were over the moon by the response that Customer Appreciation Day received last year, we just had to bring it back to say thank you to our customers.

“This year we wanted the day to be all about sharing a moment with a loved one so buy one, get one free offer is twice as nice as before!”
