Again I don't think the seller expects anyone to (Buy it now) it's to get your attention which it has done so successfully. I think there was a similar type listing surrounded by gasps and rolling eyes. None of us bought the item and I’m betting none of us will buy this but I guess you never know.
Either way if you were thinking about it you would contact him directly first and do the dance off eBay saving both of you. I sell on eBay and eBay fees and listing and PayPal fees combined together equal about 11 – 12%. So the more expensive the item the more you get the preverbal sausage. You contact him and do an off line purchase and work out the respectful deal. Just my 2 cents not asked for I know
