I was in my local asda this lunchtime and there were a few champagnes sigificantly reduced. I know someone has mentioned table wine but these are exceptional. Not sure if this is a pre Xmas clearout but there was
Canard Duchene reduced to £9 a bottle, a decent branded champagne that usually retails around the 20-25 mark.
also Asda's own blanc de Blanc reduced to £7 a bottle. A decent light champers and much better than the Oz sparklers around that price.
there were other reductions, but nothing compared to these 2.
hopefully across all stores. not sure if it shows online.
