Hi - about to put down the cash to replace my Rev A MBP. I'm looking at getting a few options added. Should I just order online and wait for it to be delivered or pop down to the Bull Ring store and get one built? 1) Online, how long from shipping date do they generally take to arrive on your doorstep? 2) Going into the store, how long does it take them to build and allow you to pick it up? I know its not an exact science, just looking for previous experience.
