Frankly there is a lot of scamming from other countries.:-D
In North America (Can/Mex/USA) we can get paid via check, money order, paypal (which has seller protection). As soon as you sell overseas you sell with no paypal protection for seller (as in subject to chargebacks).
Biggest scammers are from USA? (overgeneralizing). I can say the same that Asians are biggest scammers (their product have little quality and always bizarre things-I may still throw that sh** MSI product out at my supplier) see this statement is overgeneralization also as a japanese product is not the same as chinese. What do you do when you get scammed by them??? nothing. No warranty, or its very limited warranty. so don't give me that nonsense about scam - its everywhere. also people pay lower than market prices (sometimes) on ebay and then complain about things - reminds me of the picasso IV buyer and Amix68 guy from germany.. (thread here on a.org.) Good Sellers are worldwide same as scammers.
I think the main reason for overseas business is that its expensive. postage is way higher. then cost of accepting / getting paid is higher too. Wire Transfer, Paypal fees and often reluctance of people from outside North America to send Money Order...
I also am reluctant to ship overseas. I also see & get the same when I buy anythign from japan or europe. Who makes the most money? UPS/DHL/Fedexs of the world...
PS I bought stuff from doomy and it turned out ok...
