I've only got one thing to say to daze and tonyspoons - you should try Hart & Thistle's Hop Mess Monster V2.0 :

Tastes of nothing, appalling beer.

worst "IPA" I ever tasted

The 2 stores near me have reduced a few more beers in the last couple of days that weren't in their clearouts last week:

Fullers Bengal Lancer 90p
Brewdog Punk IPA (660ml) £1.50
Staropramen (4x330) £2.13
Greene King IPA Gold 90p
Yorkshire Bitter (Taste the Difference 500ml) 80p

It does seem very hit and miss as to what gets reduced and when/where (e.g. other people saw the Staropramen on offer last week).

There have been a lot of good offers though most are now sold out (at least in my local store).

There were quite a few half price beers in my local sainsburys this afternoon.
