Can't see order history on App Store

I want to see the history of apps I've purchased for my iPhone and iPad from the App Store. In Safari I went to http://store.apple.com/us and signed in with my Apple ID and password (I only have one). I clicked on my name in the upper right, and chose View Account. On the next page I chose View Order History on the left. The next page is Your Orders and I chose "Orders Placed in the last 18 months" from the dropdown box. I've ordered dozens of apps but I get the message "There are no orders associated with this account that were placed in the last 18 months". Any idea what I'm doing wrong?

I assume that apps I've purchased from the App Store would show up in the Apple Store?
