How do I check if I have already paid for an item that I've won on eBay?

I purchased a true blood poster from eBay, and I just clicked “buy now” instead of bidding. I don’t think I recieved an email confirming that I paid (credit card), and to track my order. I know I bought from a reputable seller (moviegoods.com) because there’s a badge on the page that says “top selller” or something from eBay. They also have like a 99% rate of satisfaction or something. I remember filling out the card information and sending it through succesfully, but I never got an email. I contacted the seller, but they’re messages are automated and never seem to answer my questions. Is there a place to check if I have paid on the eBay site?, How do I check if I paid, because I don’t want to send it through again, and end up paying twice.
