He is a scammer
He is a scammer. The second transaction goes through on Paypal, the webpage says, "the payment didn't go through" and you can't navigate the page anymore without closing the browser.
When mailing to ask if the payment went through, you get no response. Even after two emails, I heard nothing.
This guy use a smart way to trick money out of people, selling stuff almost impossible to get other places in the EU.
Luckily I didn't trust the seller and asked Paypal to cancel the payment just after I made the purchase.
My best advice: Don't let this scammer trick you and do not pay from there, though it looks legit. It seems like a few people gets their product long time after purchase but you can't contact the seller. He is knows as Ray and has several other pages where he does the same.
