This is a great deal as it you can buy a total of a litre of decent wine (4 x 250ml bottles) such as Blossom Hill or Gallo for a fiver. Normally the small bottles cost about £2.00 each so this is quite a saving, it also includes sparkiling wine.
Some of the bottles of wine on offer are:
ASDA Extra Special oak aged burgundy 25CL
ASDA Extra Special Languedoc rose 25CL
ASDA Extra Special Mas Miralda Vintage Cava 2005 20CL
ASDA Extra Special primitivo 25CL

For instance, a full 750 ml bottle of the delicious E & J Gallo White Grenache is £5.40 in Asda. For £5.00 you can have four bottles of the 250ml version for 40p less and you gain an extra 250ml!
The French Connection Special Reserve Chardonnay and Merlot are £7.02 per standard 750ml bottle in Asda, so £5.00 for a litres worth in small bottles is quite a good deal.
The smaller bottles are good as you you can have a variety of tipples during the evening and are also handy to have when you may not want to consume a whole bottle of wine or just want a glass or two after work. According to the Asda website the offer runs until 01.01.10, although I don't know if this is accurate..
