Buyer Be Aware ####

Damn not another one! This is becoming frequent on here Maybe something happened and he had an emergency or something like that. He has three positive feedbacks surely he wouldn't start scamming ppl now??
Sadly, this is exactly how they work. They do it on ebay as well..set up accounts and gain a few positive feedbacks & seller ratings (many of which are simply from their other fake accounts) then..whammm...rip off dozens of buyers all within a few days.
Account gets flagged and shut down, but they simply move on to thier next ID.
OP, if you have his mailing address, send him a registered letter, asking for a full refund or the part shipped (pay or surrender), provde a reasonable deadline (normally 10-14 days from receipt of letter) IF something has happened, like a medical issue, then someone at his address is most likely receiving/handling his mail/bills, and they would certainly contact you back.
Failing that, you will have to go scorched earth on him ( I outlined steps in another thread about a rimblow steering wheel rip off)...if you sent a U.S. postal money order, that could well be considered postal fraud, interstate commerce fraud, theft, etc.
