after doing this post Stella Artois 4% Bottle (4x330ml), ASDA, £2.00 I thought I'd check the cans, and their cartons of beer were two cases for £15, however it doesn't say if it's the 4% alcohol version or not, a bit of research suggests the "Stella Artois Premium Continental" is actually 5.2% alcohol.
