Similar to the 2 for £16 offer that's still ongoing as far as I know, I was in my local Asda last night and they were selling cases of beer for £8. Included were
Beck 20 x 275ml Bottles
Miller 15 x 330ml Bottles
Fosters 18 x 440ml Cans
Additionally, they had 18 x 440ml Tennents for a whole £7!!!
I've just looked on-line and it doesn;t mention it, so it might just be in-store only.
