Chris...
Talked to my Cornwell dealer(friend) about this thread. As you said the manufacturer makes a profit selling to Cornwell, Cornwell makes a very good profit selling it to him. They give him a high retail price....say 7200.00 bucks for the 67 inch series, but to be competative, no one pays that. He said at 5800.00 bucks he is making a thousand bucks. My dealer doesn't truck finance tool boxes anymore, not sure if other companies do. You need to have tech credit, cash, or credit card, so he gets paid period! No finance...he claims he cannot make enough money on payments, to warrant the initial money out of his pocket! it makes sense, since it would take 1 to 2 years..if he is lucky to get his profit. That's if a deadbeat doesn't make off with it. How many newer boxes on ebay, do you think are actually bought and paid for??? I'm thinking not many..hence the new policy. Depending on the box cash or credit(dealer paid right away) is considerably less than any list. I'm not in disagreement with your post....just a additional perspective from a dealer.
You have some good points, especially on why it is changing.
Cornwell has a slightly different tool sale model than the others. And company supplied credit is another method that is gaining popularity, as the truck guys have more and more problems collecting, as you point out.
On bigger ticket items, like super big boxes and scanners, the company makes more profit and the truck doesn’t carry as much of the credit load, in that the credit is extended in a more normal fashion by the corporation, who thus makes a lot more profit.
A ‘7200’ dollar box would not go on the 50 bucks a week program normally, anywhere, because it would be hard to safely risk that much captial, hand tools are the big money maker on credit, and the lesser boxes.
Recall though, it's about the cash flow, not the sale.
About the dealer, who I suspect is a heck of a nice guy;
He says he is making a thousand bucks on a top end box.
That’s much higher than I’ve ever heard a dealer suggest he is making.
If you talk to most dealers they will assure you they are practically losing money on every transaction.
Car dealerships, even in the boom times, always lose money on every sale. Really, just ask them…

Seriously, ask any businessman and one in 100 will admit to making a profit.
This is actually the best policy, after all, do you tell everyone that asks YOU your hourly wage, salary, benefits etc.?
Especially if you are trying to sell them your products or services?
It’s a truism of human nature to not want to pay ANY profit to a business, even though we know it’s silly to think the place should sell the stuff for free.
So any businessman worth a sack of used road salt will never give you the idea he is getting rich, or even making a living, on your sale.
If he’s smart he will cry poormouth all the way to the bank.
When I worked for dealerships the owners always told us how poor they were. I would always admire their new Ferrari, or Rolls, then have to listen to the sobs about how much money they were losing that week. Part of the job.
