So I'm curious about something. I was ready to make a purchase on a site that accepts PayPal credit, when I thought I'd check my balance before making the purchase. I noticed that I have a limit of $1,330 and have used up about $714. But what is weird is that my account shows that I only have about $300 available. I'm confused? Shouldn't my available amount be $616? What gives? Why is the credit limit different from the available amount? Thanks.
