I briefly looked into this, but I wasn't convinced the juice was worth the squeeze. My cash is automatically getting ~4%, but there's too much fine print to make sure the BNPL rate really is 0%, I'm sacrificing 2% cash back, and missing one payment makes the whole endeavor negative ROI.
I suspect this is where some buyers will get into trouble. Theyll think they made a payment, or they miss a notification that tells them to send this month's payment to servicer X not Y, and before they realize, boom they are in default and owe all the interest.
