Error when buying on eBay

[Laurelhoff]

I'm having an error with my Student Account when buying on eBay.

When it processes, it sends me to the payment page and shows $0..it says I don't have enough money in my account, which I know I do.

My permissions are set right and I should be able to spend my money..but I can't.

I tested it with something less expensive, $1 to be exact. It worked fine and I would have been able to buy it.

But for some reason I'm not able to buy what I want. 

I'm not sure if this is a problem with ebay, paypal, or the seller!

Here are some screenshots:

However I am able to press continue. It loads and then I get this:

EDIT:

I was able to buy something else for $17 something...hmm
