Ideal for Christmas (well, with the best intentions anyway!), Sainsbury's have Eaglecrest Chardonnay at £2 a bottle to clear. Buy 6 bottles and get 5% off = £11.40
I bought six last night and there was still some instore today when I went in again.
They also have their own Limited Release at £2.50 a bottle, and you can apply the same 5% discount to that when you buy six.
