The Superdrug meal deal offer has been around for a while, buy sandwich and crisps and get bottle of coke free.
But i've noted recently they now sell a range of 'Sutherland Deli' sandwichs for £1.29, so the meal deal (Sandwich / Walkers Crisps / 500ml Coke) comes to only £1.71.
Also, if you buy two the till discounts further for buying 2 cokes and 2 crisps and totals only £2.68, so only £1.34 each -
The Sandwich range isn't exciting but they are suprising nice. Cheese and Onion / Ham and Cheese / Tuna and Sweetcorn / Egg Mayo & Cress
