ALL of these platforms depend of people being late with their payments. If you set up auto pay and have the money in your account it's a no brainer.
Especially with buying something like an Iphone. Instead of doing a 2 year commitment you can bring an unlocked iphone to your carrier and have it paid off in a fraction of the time.
I used Klarna to buy all my apple tech. The money I would've spent up front, I end up saving.
This is something you can use to pay save money in the long run. So instead of paying $1000 up front, you can put down $250, put the other $750 in savings and make 3 payments of $250 and act like that $750 was spent.
But a lot of people will use the $750 to buy something else.
