Shame you mist the Friday auction Vicky, you could have out bid my alcohol induced bids on the grandstand tickets (donated by the Man, himself Big H!), but as you say all for a great set of Charities.
As for the Justin Wilson goodies, why don’t you open it up for bids here on the forum, and then use any bid as the eBay reserve price (unless there is a bid considered by the committee as enough to avoid eBay), that way CA's get 1st bid.
