Have noticed as well he's removed his postal address from his website ( I found it on an old Google link ) - so maybe hes expecting a lot of dissapointed buyers shortly
I'm not that bothered as I can easily get my money back if he doesnt deliver, but I noticed all his auctions now dont have paypal or cards as an option, only cheques, PO's etc.... so I dont know if hes trying a scam, or is just an unfortunate middleman being let down by a supplier he has no control over.
Does remind me of some good Ebaying advice though for sellers - never list anything you dont physically have in your possession !
