So i found out that when i bought my Macbook Pro a two weeks ago from Bestbuy that it was in fact an open box item that was un-marked. I found this out because when i went to my local Apple Store to purchase the apple care package that the serial was registered to someone else. I called apple from the store and they quickly swapped the reg info but i had to wait for 24 hours for it to go through and so i could not buy my Apple care the other day. I quickly went to bestbuy with my MBP and the box and they gave me 100 off the item because it was in-fact an open box however it is from March 2011. Is it worth the extra 100 dollars for a late model 2011 MBP? i currently have the 15 inch i7 quad, 8gb memory upgrade and 500gb HDD.
