As mentioned previously wine at Tesco's has 25% off when you buy 6 bottles.
However if you buy 8 mini bottles for £10 you also get 25% off the full price of the 8 bottles. Jacobs Creek £2.29 a bottle gives you the best result if you like it. You have to buy 8 to be more than 6 and get both discounts. I paid £5.72 for 8 bottles, but i got a mixture of £2.29 bottles and £2 bottles.
Good for stocking up! Or getting very drunk and passing out on park table :)
