As an amusing update to this, on Friday I went to the fucking shitestorm of an Iceland in Southmead Bristol. Easily as awful as feared, and no beer in sight. I went home dejected.
However, on hearing the news that I was attempting to shop at a budget supermarket, the aforementioned snobby girlfriend went on Ocado and discovered they are selling three of the Meantime beers at 75p a can. 75p!
She ordered 40.
