You can get those machines at through a wholesaler. I usually win deals against the "dealer" wholesale buyer. I say I can get the machine as well as anyone else. But who is going to fix it. Then bring in a copy of the Locator and show them that anyone can buy the machine they are looking for. Show the Value of going with you rather than the price of going with them. If they are buying only on price you probably don't want them as a customer anyway because the will question every bill and be a pain in the butt.
Sometimes you have to walk away.
Good Luck!
