It's a scam scheme for financially illiterate people IMO. The fact that it's added into a default browser in a most popular OS in the world adds insult to the injury.
I've even been overdue on a bill (I forgot about it) and they just sent me an email asking to pay, still no fees.
Of course if I had continued to neglect the bill, fees might have started kicking in at some point, but that's no different from any other postpaid service.
If I'm reading this right, the late payment fee is maximum of $7 for their 4 payment thing?

If you bounce a check or an ACH the fee seems to be $27 (but not more than you owe) for their 30 day plan: https://cdn.klarna.com/1.0/shared/content/legal/terms/0/en_u...
Their pay over time thing seems to be 0-29.99% which seems in line with credit cards?
I mean, sure, I guess making it easy for people who make bad financial choices isn't great... but it's also easy for people who are making good financial choices.
