I was in ASDA Newton Mearns this evening and there is a fine selection of ales selling for £1. Ales such as McEwans No 1 Champion, Innis & Gunn, Belhaven 80/, Belhaven Twisted, Belhaven Fruit Beer, Guiness Foreign extra, Wychwood Goliath, Newcastle Brown Ale, Cobra amongs others. Some of these available online.
Reckon beers going for £1 will differ accordng to location. In Newton Mearns there is plenty of Scottish ales certainly going for £1. Even better for me got 10% staff discount via my wife hence beer just for 90p! Fridge now well stocked with beer.
