Every once in a while there are multiple parties structuring a deal where someone is left with a bad deal when it’s all said and done. As a consumer, you just have to make sure it’s not you.

But take, for example, the early days of Moviepass. You pay a cheap subscription to a service, and they buy you unlimited mobile tickets at the theater. Too good to be true in the long term, but in the short term it was a good way to spend some money that venture capitalists were giving away basically for free.

Businesses aren’t always smart. Sometimes they make financial mistakes and it’s your duty as a responsible consumer to punish those businesses for those mistakes.

In the case of dealer/manufacturer/financing incentives and the individual salesman commission, sometimes the kickback/fee scheme leaves someone else holding the bag. If you can negotiate a lower sticker price because it comes with some predatory terms on financing, but there’s no penalty for prepayment, it might make the most sense to take the low sticker price (made possible by the lender paying the dealer a kickback for the loans), finance at high rates, and then pay the whole thing off as soon as you can, so that you get the “discount” without having to pay high interest/fees, then you walk away with a good deal in exchange for just a little bit more hassle and paperwork. Sometimes the incentives swing the other way, too, where the lender is affiliated with the manufacturer and needs to juice sales volume by offering below-market rates on financing. As long as you can actually see how everything works and you can find the pain point, it may be possible to get a good deal and dump the bad deal on some faceless corporation for them to worry about.
