We always spent as little as seemed reasonable - £5.99/bottle seemed OK to me. That was when we were drinking a fair amount. This summer we went wine tasting and enjoyed putting more thought into what we were drinking and when we came home we thought we'd join The Wine Society and start being more discriminating. So, we've paid a bit more, not more than £10 though. Now Christmas is coming and we could do with getting some sparkling wine in and I'm trying to decide how much to buy and how much to spend. Majestic have good discounts and the Wine Society sell cava at £9 ish, prosecco a bit more, so not that different to Sainsbury's frankly. What do you do?
