So I just looked at my credit card statement with my ibook purchase, and it seems I was only charged 949.05, even though I upgraded to 80g hard drive. So now my question is: did I get the upgrade for free, or did they send me a stock book? How can I check and make sure? I know this is a pretty basic question, but I'm new, and I didn't have any luck finding an answer in help or by searching forums. Thanks.
