Hi Guys, I'll be heading over to the US from Australia soon and I'm looking at picking up a new MBP over there. But I would prefer to get the 13' inch, non-touchbar. I'm currently running a mid-2012 model so I'm overdue for an upgrade. However, I want to pick one up with 16GB of ram. I've heard that some of the larger Apple stores in the US will carry higher spec'd/custom models, but do you think I'd be likely be able to pick one with more RAM up, or am I stuck with the standard spec? Any help would be appreciated.
