apple online receipt

I finally ordered an ibook today after patiently waiting for the update. I also order the 20gig ipod (Student Union deal). I'm wondering though when I will receive the receipt for these items, and since they are being shipped seperatly, will i be billed for each item at different times or will they show up in the same transaction. I'm only concerned about this because in order to use the Student Union rebate the 2 items must appear on the same receipt. Anyway, thanks in advance for anyone who can help me out.

I think it will appear on the same recipt.

If they were in the same 'shopping cart' they should be on the same receipt.

Excellent, thanks.
