Ready to purchase. Now what?

Alright! Finally ready to buy my dream camera. I just wanted to verify with you all what I've learned from reading about buying this camera.

From my understanding, people seem to have the best luck by directly calling a Best Buy call center and speaking to a real person. They can help you track down the nearest camera, or put you on a waitlist...???... I understand that I'm probably looking at a few months before my order is filled, but I wanted to make sure this is the optimal method. My other options are of course B&H or Adorama.

Anyone have any input or guidance on my journey?
Thanks!
