I've tried searching but I guess chances are already posted...
Just picked up some 330ml bottles of Hoegaarden at Sainbury's for 70pence a bottle. The beer has an expiry date of June 2009
I haven't checked online.
Edit: As is suggested below - this may well just be a local offer, so probably not worth making any special trips, but no harm in checking it out if you're already visiting a Sainsbury's. It did have a proper label that quoted the name, price, and cost per litre.
