Tesco currently have Blossom Hill white zin on offer at £4.00 but if you buy 6 you also get an extra 25% off making it only £3.00 per bottle.
Went shopping today and bought some so I know it works.
Good price for nice wine.
I think the extra 25% off is just instore, but not too sure.
I've linked to Tesco wine when I should have linked to grocery. It won't let me edit it though!
