Sainsbury's offer. You can buy any six bottles and get 25% extra off. So you could buy 3 bottles of wine and mix and match to get one bottle of this nice champagne.
Usually £40, so at almost half price, it's handy for the festive period or any upcoming celebrations.
I can't see the stock holding out for long as this is cheaper than all alcohol stockists, so this could be out of stock shortly, lasting until the end of the 6+25% case offer.
Grab it whilst you can.
P.s if this isn't your thing there are some other great wines on their website.
