This is incorrect. SJ absolutely kept around the older iPhones, iPods and at least one older MacBook current as value-based alternatives to the newer models.
I'm not at all surprised about price increases (that won't be confirmed until products hit the streets) seeing as there is a chip shortage, Apple losing money due to COVID because they had to close stores plus with the chip shortage they would need to control inventory. Heck Sony announced there will be no Playstation 5's until late 2022-to early 2023 due to the chip shortage.
