Asda have a good range of wines in the 3 for £10 offer. Lindemans Shiraz Cabernet 2007 and Chardonnay 2007 are £8 each but are included in the offer. Tried the red on Monday and the white on Tuesday, both are nice so picked up 45 bottles today for our wedding reception. Paid £150, with a saving of £210. :-)
Not sure how long the offer is on for, or if it is available online.
