Hello! I bought a MacBook Pro on the 26th of February, and iWork along with it. So today when I was filling out the rebate form for iWork, I noticed that it asks for the UPC codes on the computer and the iWork, along with the receipt. Well, that had me worried. If I sent in my receipt, and both of the UPC codes... I would have no way of proving that I bought this product, if any problems ever occur! Is this how it is supposed to be or am I missing something here? Thanks!
