Interesting that all the bids are set to private. I know ebay no longer shows who is bidding but this seller took it a step further and set it to private, you cannot tell how many different people actually bid.
Another thing that happens alot, and has happen to me, is the buyer well shill bid and sometimes he outbids the highest person so he/she ends up being the winner so he does a 2nd chance offer very shortly to the next highest bidder.
"the ebay offer came via Italian branch ..."
not sure what you mean here, but if someone is Italy making a 2nd chance offer to you for someone in Thailand, that throws alot of red flags.....
Do not always count on Paypal or eBay buyer protection when it comes to international sales even though they claim your safe...
Also user has only been registered since April 2010 and this is there first eBay experience as a seller or buyer under the ID.
If I was you I would pass on it...
