Bill me later ebay payment

[purplepanda]

Hello, not sure if this is the right place for this, but I recently bought some headphones on ebay and used the billmelater paypal option because there was a $10 offer with it. I have used this option before, but it still acted like I was new and asked me for my birthdate and last 4 ss digits. Anyways, all the other times I have used it the payment shows up right away on my paypal account history and I proceed to pay it off a few days later with my paypal balance. But this time the headphones charge still hasn't shown up after almost 4 days, even though on ebay it says it has been paid for. Is it normal for it to take this long to appear on my account history?

Thanks!
