all I can say is that some business people are in the wrong industry.
my father spent his whole adult working life in service industries and he always used to say " if you aren't providing the service you are in the wrong industry."
this guy is not considering his customers at all, just the $ in their pockets. also sounds like possibly setting himself up as a bit elitist with his customers as " Him "No never thought of that, none of my customers have any problems with money"!!! "
don't worry chris, I have run across people like him before, they need to either completely corner the market or wait till their stock is all that's left before they can get everyone paying the prices they ask.
as for buyers keeping the prices down, that only happens when the buyers know the other options like it sounds like you might in this case. otherwise, it's the competition which keeps the prices down.
if the place you are buying from were to advertise in your local area they'd get the business from the sounds of it but obviously the guy's other customers either have a preference for his parts or they have too much money or simply couldn't be bothered trying to find the best price.
you don't buy the first car you see do you? so why pay the first price unless it is found to be a prime part and no shipping to pay and the guy's not trying to rip you off or similar?
just out of curiosity, the $600 part, how much incuding shipping to get it to your door?
reason I ask is there was a guy here who'd sell people something and then go buy it from a cheaper competitor. he even charged shipping to the customer and the place he was buying it from was paying it included in their price and was shipping it direct to HIS customer. be interested to find out if that might work there in some ways ( If it does I'll gladly accept a commision of 1% of the net.
