ok, thanks for the quick information!!! Is it safe to assume that all Leopard single packs will be the same model number?
I bought Leopard on Friday night but haven't opened it yet because I had not bought an external HDD and I did not have time. This got me thinking that maybe I should just wait and order from Amazon and save the $28. However, I was wondering if I could just open the copy I have now, then order it from Amazon and return that copy to the Apple Store for a refund.
When I called the Apple Store to ask, the lady said it would not be a problem as long as the part numbers matched up. I asked why this number would change and she said that sometimes part numbers vary depending on which store you bought it from. The example she used is that an iPod bought from Best Buy or Target might not have the same number as one bought from the Apple Store.
This did not make sense to me, so thank you for clarifying!
