Tesco have a 3 for 2 offer on loads of packs of beer and some single bottles.
Most of the deals aren't that great, as they've put the prices of many packs up to coincide with the offer. However there are some stand out deals:
12 x 440ml cans of Becks Vier for £6.00.
12 x 440ml cans of Budweiser or Red Stripe Lager for £7.98
12 x 440ml cans of Blackthorn Dry Cider for £5.82.
3 x 750ml bottles of Hoegaarden Wheat Beer for £5.56.
