have never seen a single Apple product be sold out in their official stores.
Demand for Apple products is surely predictable enough that Apple knows how much inventory they need for product launches, the holidays, etc. I know there have been sellouts in the past, but I think it's been a while since Apple has made a product which really sold a lot better than they expected.
same thing with GPUs. even during the gpu mining craze you coukd find any GPU at double the price, as many as you wanted.
This is definitely not true, if you restricted yourself to buying from actual stores and not scalpers. Even allowing for scalpers, there were periods of time when Newegg had just zero of many upper-end GPU models available for purchase.
Sony did the same with the $500 msrp PS5, claiming scarcity yet selling at $700+.
Their usual thing was selling console + game bundles. That was a way they could increase the selling price with only a small increase in costs.
On Amazon, it took until early 2023 for them to remove plain PS5 consoles from their waiting list. They didn't call it a waiting list, but described it as "by invitation, only" which you had to apply for. About the same time as they started selling it normally, Newegg also had it in stock and not as a bundle deal.
I then waited until their October "early Black Friday" deals to get one at a $50 discount.
Definitely not. Most of the inflated GPU pricing didn't flow through to AMD/Nvidia, but were rather eaten up by scalpers, graphics card makers, some wholesalers, and some retailers.
Likewise, the inflated console pricing didn't really flow through to Sony. Sony makes most of its money on software and services, selling the hardware at very little profit (usually at a loss, in the early days of a given generation). More consoles in more people's hands means more software & service revenue for Sony, so they
absolutely had their incentives aligned with getting more consoles into people's hands.
in reality they are sitting on millions of units in the supply chain.
You really shouldn't say such things without evidence. A lot of us witnessed what you're talking about, firsthand. I keenly payed attention to exactly
who as selling PS5's and GPUs - i.e. whether it was the store or a scalper. It was really the scalpers who had nearly all of the units you're talking about. Most of the big retailers and e-tailers were pretty good about not selling at hugely-inflated prices, whenever they managed to get some in stock.
