Bottled Ales are £3.99 for 3 in Lidl at the moment, including Hob Goblin. Usual caveat regarding situation in your local branch.
Norman P supports responsible drinking.
Lidl often stock Hobgoblin and have it on offer. I used to enjoy a bottle of Summer Lightning but for some reason Morrisons and Waitrose don't stock it anymore round here, which is a shame.
