OK I know this is a repeat, but from 10 months ago.
Seeing the other posts at higher prices prompts me to remind people that Booths run a continual stream of £1/bottle offers. This evening I bought Marstons. Last week I bought Jennings and courage.
Generally three or four different beers.
They also had some half price champagne (£12/bottle - no idea if its any good - I'm more sceptical about wine offers)
