You never know what was actually happening, the guy at the shop may have wanted the receiver for himself to fix as cheaply as possible and sell online. So you may have prevented the guy from a self righteous pay day. Why do you think the guy in the shop wasn’t answering you when you asked about the receiver ???? The guy at the shop was trying to scoop up on a deal and probably gave an expensive prognosis of the receivers problems just to separate the receiver from the owner.....and then along comes you !!! Why else would the guy at the shop blow you off ??? You saved the receiver from an opportunist that would have done a minimal repair just to make a quick couple hundred bucks and whoever would have bought this receiver from the guy at the shop would have sent the receiver to recycle after the cheap repair job failed. You didn’t cheat the owner of the receiver....you just picked up the peices and saved the receiver !!!
