I've recently added a payment plan for my phone contract to paypal credit, and it appears to have added the full sum of the purchase to my credit account. It does say that it has 30 installments etc. until it's paid off so this isn't the issue.
How is the money spread within my account and is it possible to pay off an item before the others? How does paypal select where the money I payback goes? Is it the lowest costed item? Highest costed? Or is it all items get a share of the money I pay?
