I do less PC building these days, but I, too, shop with B&H if they have what I'm looking for (which is nearly always).
I did use them once last year for RAM. Took them 2 weeks to ship, then I cancelled the order. They shipped it anyway.
Although the overpriced premium cables are definitely still a thing...
After multiple rounds of that they gave me a phone number for the seller itself, which, when I called it, turned out to be something like a 2-person shop. Their recorded greeting said that they were on vacation for an extended period starting from before the date I ordered and upon which they printed a shipping label (which was presumably printed by a shell script or something).
Multiple more rounds of trying to get a refund from Newegg later, I just did a credit card chargeback.
That's standard practice for pretty much all of Big Tech. Official support channels? You can go fuck yourself. Get lucky and frontpage reddit or HN? They'll finally honor their commitments and put out a press release about how $BigCo is committed to $generic_ideals.
I watched a couple of the Gamers Nexus videos, and even the most charitable explanation is pretty damning. One of the related links on YouTube was a former Newegg RMA inspector, who gave some background on how things used to be done. Even if this is limited to open box items, which I would rarely if ever buy online, it gave me enough pause to pass on the SSD deal.
