I just got my MBP 2 days ago. I got the 2.8GHZ 15' one, the only thing i changed was HD. Rather than 500GB HD, i got 320GB with 7200 rpm. Is it refundable?
OP, if you want real answers and not speculation you will ask your Apple Store
Experiences vary by store, by employee, etc.
Your attitude, etc. can also have an impact
