Re-naming Valentine’s Day ‘Customer Appreciation Day’, the high street sandwich shop are offering the free 6-inch sub between 11am and 7pm when you buy a large dispensed drink or bottle of water (which cost around £1.50).

So, there you have it, simply pick a drink and then bask in the glory of your own free sub, it's that simple.
