My first post!
I mentioned this in another thread but thought it deserved one of its own.
Tesco include the Wairau Cove Marlborough region Sauvignon Blanc in their 3 for £10 offer instore (single bottle price £9.99). When I bought 6 bottles I expected to pay £19 (£20 less the 5% 6 bottle discount) but it gives a £3 discount so £17 total or £2.83/bottle. I've now done this several times in different stores (hic!) so I know it works.
To be honest it's not a £10 wine, but it is a very flavoursome mouthful and the Marlborough SBs don't come cheap. At this price it's a steal.
Initially little stock but my local seems to have got a lot more in. Look out for cases near the checkouts too.
