Sainsbury's are obviously having a clear out of some of their wines to make way for new stuff. There are many wines marked 'SALE' and really cheap.
I bought Monmessin Beaujolais Villages for £2.50 a bottle, but there are a range of rose, whiltes and reds (gallo winemakers seal, Oz and Californian White Zinfandel, Chardonnay, shiraz etc) all down at least 50% to between £2 and £3 a bottle.
if you fancy something special, there was also a Jadot Meursault down from £24.99 to £12 a bottle. 2006 vintage.
some great deals to be had.
would assume they would go quickly as I cleared out the beaujolais mentioned above.
