Just popped into my local Tesco (Twickenham Extra) and they are clearing all craft beer and cider to make way for Xmas drinks. Loads left as of 1 hour ago. Not sure if local or nationwide, but prices i got are:
Brooklyn Lager ×12 cans £6
Goose IPA x12 bottles £6
Pistonhead Lager £0.88 per can
Orchard Pig Cider £1 per bottle
Stock up if you're nearby!
