Exactly the same happened to us! We sell roller derby skates in Australia. He said his customers in Thailand had inquired about the products he wanted to order... problem is a couple of them are custom skate builds that we made for our mates here in Brisbane and no one would even know about outside our group of friends or visiting our website (which doesn't have that much traffic from Thailand!)

We emailed him a quote and he sent us the information about the shipping company mentioned above (same addresses and phone numbers etc.)
We suspected a scam but everything seemed relatively legit (in an unbelievable way!) until it mentioned that the merchant pay for shipping with payment to Western Union. The only info regarding this scam we could find was this page by googling the phone number. We even google earthed this [***].
