Two purchases using Paypal Credit – how to pay?

Description

Hi I tried to search for this question but couldn’t find what I was looking for. If it has been answered somewhere, I apologise. I have purchased something via Paypal Credit which was ú67. It appears as current balance. There is no due date so I called the Paypal customer service to set a due date for me and I was told that when bill will appear on 9th of June, it will come with due date. Fine but I had another query. And in the middle of explaining him about my issue the line was suddenly disconnected somehow that was really strange. Anyway, my second query is I want to make a purchase of ú300 which will have four months interest free period as I understand. How will my two purchases appear in the bill? Two separate so that I will choose which one to pay first? Or one of it will have priority over other? For what it worths, I am in UK. Please clarify. Thank you
