Because you should get down there NOW. They are selling some spectacular 1st and 2nd growths (Lafite, Latour, Montrose, and more) at I'd say no more than 30% of the current market price.
If you go and pick up a case for £900 you can sell them for £2000-3500 depending what you get.
They are only there this week, what doesn't sell there then goes to Reading and then I can't remember where. So first pick at Bristol (well, second pick actually, PrincePeahead has just spent so much money there that the Manager personally loaded his car for him. And a jolly nice man he was too )
