Outrageous overbill by Kanter Automotive

Does anyone know what the "retail" price of the rebuild from that rebuilder actually is? The retail price might be what he was charged, then he saw the wholesale price that Kanter gets and expected that price. Even if he went directly to that rebuilder, his cost might be exactly what he paid thru Kanter. And who's to say what is an outrageous mark up if you don't even know what a business' overhead is. If you knew what the mark up on everything you bought was, you'd think that a 150% mark up was a deal. If you know before hand what something is going to cost and you decide to pay the price, don't go complaining that you got ripped off after the fact. If there is a problem with quality or workmanship and the company you got it from won't fix the problem, then by all means complain all you want.
