7dayshop have produced a new range of batteries. I was tempted by the CR123a’s for £4.49 for 4, but noticed the expiry date is 2015, which is very poor for a lithium primary.
Still, £6.99 for 40 alkaline AA’s or AAA’s might be handy (if Don Kidik’s 100 for £14.99 find is too many) coming up to Xmas.

Not sure whether they ship to rest of EU - they are based in Jersey.
