How do I check billing history in iTunes?

I get an email notification from PayPal that a payment was sent to the iTunes Store. No email from the store. No info other than transaction ID info in my PayPal account.. No description of what I purchased. Haven't purchased anything lately. I just want to find out what I was billed for. Possible it was something I forgot about. Went to store site could not find anything that shows billing history. Any way to review billing or transaction history for iTunes Store purchases?
