It warms my heart that Boeing has pricing information available, even if it's just average prices. I hate that "Call Us" where the price should be and needing to go through excruciating pitching by sales droid to get further, I'll ask them how their product is more special than a 747 next time....
Without providing an easy way to pay they are losing lots of potential customers. If they just added a simple Stripe form, their conversions would double overnight.
Fee = $360,000,000 x 0.029 + $.30 = $10,440,000.30
How much does a phone line, a bank account, and a sales-person costs on average?
They could really reduce that fee if they started accepting payments in Bitcoin!
It is tempting to go with this line of reasoning :-) Although the more salient point is getting a better handle on predicting the return on an investment. I'll admit that I've bought a third party accessory that I was "pretty sure" would work with something, only to find out that it would not, and then being unable to return the accessory. That really was money down the drain. My wife, being much more frugal than I, has pretty much trained me out of that habit. And of course it is especially dangerous in business.
