Just a heads up on this cracking offer. Saturdays The Sun and Sundays News Of The World will both be carrying vouchers for a free six pack of Walkers Crisps, redeemable at Co-Op and Somerfield stores.The Sun is 60p on saturday, making this deal pretty impessive (Walkers six packs usually retail at £1.39). Naturally it's subject to availability and all that jazz.
Hope it helps! :-)
