It's never how much you sold it for the real question is "how much did you buy it for?"
The folks who have had long relationships directly with train importers have the deep discount deals and they order in quantity.
In my other business there is the courtesy 10 or 20 percent discount, then the commercial or dealer discount of 40 percent, then the long deal is 60 percent WD or warehouse distributor discount.
Of course buying overruns is the greatest deal going. Very sharply cut pricing. However, BTO is killing that situation.
With overhead today one needs to have a heavy spread to make it in the long run.
