He replied to my message today. It looks like Fedex screwed up the tracking number. He said he got the parts the day after he had his bank stop payment because the tracking number showed invalid. Now he said he will wait a week to send me another payment but I question why wait a week since he has had the parts for a week already. I dont think I will take any more checks though. I hope this is all a misunderstanding and that he didnt stop payment and skip town as soon as he found I shipped.
