Morrisons Vintage cider is down to £1 a bottle at the Rochdale store. This stuff is normally in the 3 for a fiver deal and that is good value, so at a £1 a bottle it'd be rude not to take advantage!
As I say, I bought it at the Rochdale store so unsure if it is nationwide.
Oh, it's 7.3% btw so be careful! ;)
