I think this may only be available in stores which have stock left.
As per title, you can currently buy 8 x 500ml bottles of Bavarian Winterfest Beer for £8.04 at Marks and Spencer. This is 5.2% ABV and is brewed at the Arcobrau Brewery in Germany.
The bottles are £1.49 each and along with all other bottles of beer in M&S are on a 4 for the price of 3 offer. In addition, if you buy more than 6 bottles, you qualify for the 10% wines discount, which brings the price down to £8.04 for 8 bottles.
I had the last bottles in the Exeter M&S, but they also had Czech (5% ABV) Lager at the same price.
