WED clay in the UK - interest?

Hi guys, not sure if this should be in the cargo hold, but I don't actually have it for sale yet, so I'm putting it here in order to gauge interest.

I'm planning to get hold of WED clay and make it available for sale in the UK alongside my Klean Klay: http://www.propbuilder.co.uk/products.html

It'll be about £10-£12 per 25lb (~11.25 Kg pack), with something like a 10% a discount for 50lb (that's the actual price, not +VAT). Postage to the UK mainland of course won't be that cheap, but I'm investigating low priority budget couriers.

Does this seem ok / has anyone used it or anything similar / cheaper in the UK before?.
