How can I tell if a book was delivered back to Apple for wrong delivery?

I recently bought 3 books from iPhoto, but with a different address than my previous orders.

They were supposed to have arrived already, but they haven't. And I also noticed a refund on my bank account.

I could order the books again, but I would like to be sure that they won't be delivered ever again, otherwise I'll end up with 3 extra books that I don't need and with less money on my "pocket".

Can anyone tell me how can I be sure if the books were returned to Apple?

Thank you for any help!
