A little over a month ago, the laptop I wanted (14” MBP, M1 Max, 64GB/2TB) was showing 2+ month ship times on Apple.com but it was in stock at B&H Photo and I picked it up the same day. YMMV.
That is completely different than what's stated, though. That is "B&H bought this months ago, and Apple happens to be back-ordered on the same (I'm assuming more-or-less standard) configuration."
This is about a custom order from Apple directly vs. a reseller ordering that custom configuration from Apple.
