I bought another MacBook Pro for work last night on our way home from dinner. I stopped at Best Buy and they had an Open Box, with the just the specs I wanted (2.9Ghz, 8GB..etc) but this morning as I set it up, the specs are that of the lower model (2.5Ghz, 4GB..etc) and now looking the serial number of the machine doesn't match that of the one on the box. Best Buy hasn't opened yet for today, but how should I go about getting this taken care of? Ask for a brand new of the specs I paid for, just ask for a refund..? How would you go about this?
