profit per sale

What will the effect be on the profit per sale?

And hidden costs are easily forgotten, so your true profit per sale is often lower than you realise.

It is generally a big moneymaker, with new-car dealers averaging more than three times the profit per sale on used cars than on highly competitive new-car transactions.

That is, firms may be indifferent between posting a high price (thus selling infrequently, because most consumers will search for a lower one) and a low price (at which they will sell more often, but earn less profit per sale).

Profit per sale across different vendors is only a concern if the TOTAL profit can not be increased dramatically through the arrangements made, and in this case, the vast majority do make more money selling millions of copies through apple then they do a few tens of thousands on their own.
