I would heartily recommend keeping a weather-eye open at Lidl. Their stores across the country are offering 500ml bottles of Wychwood and Shepherd Neame beers (such as Bishop's Finger and Hobgoblin) at £1 a throw.
That's £1.14 a pint for an excellent beer - compared to well over double that in a pub.
As always with Lidl, though, blink and you'll miss it. We've just bought an excellent guitar set for £30 for a Chrimble present for a loved one (it's alright - she never reads this rubbish). But it was one of the last two on offer at our local store.
