FICO to incorporate buy-now-pay-later loans into credit scores

This would probably only affect the people with the worst credit scores I imagine. I just don't see a ton of 800+ credit score people deciding to spend 5 payments of $20 for a pair of $80 shoes.

Shifting a cost forward a couple months interest free is a great deal for people who are financially responsible, especially if you have some other loan (like a mortgage) that you could be paying off more of instead.

It's no different to the practice of using a credit card for everything and then paying off in full a month later because the credit card interest is lower (often zero if you pay off within a month) than the mortgage interest.

In the case of a 0% grace period sure I agree, but otherwise in no world is credit card interest cheaper than a mortgage over the same time period.
