Forget having to splash out on an expensive restaurant menu, - you can pick up a 6-inch sub of your choice on the national day of love. But you better get your skates on as the offer is only valid until 7pm this evening. Here’s what you need to do to take advantage of the mouthwatering offer: It will only be available at certain Subway stores, but the company has released a list of everywhere that you can get hold of your 6-inch delight. See the website full list of participating places. What does the free 6in sub deal include? The incredible deal allows customers to choose a free Subway sandwich of their choice when they purchase a large dispensed drink or a 500ml bottle of water. These are priced at around £1.50, with a typical sandwich usually costing at least £3. The company says it has launched the Customer Appreciation Day “just our way of saying thanks.”
