The whole “buy now, pay later” deal is a credit loan. They are most likely paying the merchant directly and using your loan as collateral to speculate on the market, until you pay them back for that loan. If that’s true, they are making profit on the interest gained from your loan.

I’m not very educated in economics, so I’m struggling to understand this. Is there a way to easily explain this? I’m 38 so… please use big words if you like, but simple domain language. 😅
