I visited my local Seven Sisters Tesco store tonight to buy some apples & pears and while wondering around found a heap of large packs of Beers at reduced price. Looks like they were just trying to get rid of it....
Boddington 15pk £6 (pictured i attached - the only thing i could carry home being on foot)
Budweisser 15pk £5
Guiness 18pk £7.50
Bulmers (not sure of price or size)
A whole heap of different red and white wines all at half price
Not sure if this is nationwide, but they had a quite a few of each, considering the sotre was heaving with customers.
