I've seen these deals for ages in my local WalMart Asda's etc. and never really paid much attention - however - the small bottles (25cl) are 4 for £5. Although this may not seem great, it works out at £5 per litre of wine.
I know that this deal will get slated, but if you are like me and fancy the odd glass of vino without cracking a whole bottle, these are perfect and good value too. There a wide variety of red, white and sparkling wine.
For info, 25cl is equivilant to a large glass of wine from a pub. Nice.
Drink responsibly, HUKDealers!
