I think there would still be a supply for refurbished products (maybe a bit less this time with the shortages) – as Apple cannot sell open-boxes or returned products as new.
Not All Apple refurbished products are created equal though.
Apple have literally the BEST condition you can expect on any refurbished product on the market.
But all other refurbishers (Gazelle, Mac of All trades, Amazon Warehouse, Decluttr...) grade them in a scale (A, B, C) based on their cosmetic condition and add a year warranty as well.
That was exactly my pain point back in 2007 when I wanted to get a specific configuration for the retina Macbook Pro.
That's why I built RefurbMe as a comparison and monitoring service :)
First, inspecting all network requests that are happening on the web client. That helped to inspect all requests made to read a page and edit content (a lot of data is transiting, maybe that's why it's slow on the startup...).
And then I realized there were few existing open-source projects that already done that (https://github.com/kjk/notionapi and https://github.com/jamalex/notion-py), but there were lacking an HTTP API endpoint so that we can easily plug them that to Zapier/Integromat or a Webhook.
These two repo didn't had a way to convert a Markdown to a Notion content - which would make it complicated to know every type of blocks that makes a Notion page.
Finally you needed to be tech-savvy to be able to deploy the open-source projects and there wasn't any simple integration SaaS out there – so it was limiting a large section of people who use Notion extensively, and are familiar with automation tools.
http://www.refurb.me/ is monitoring service for the official Apple refurb store. Because it's hard to know when the product that you want to buy will become available. RefurbMe will alert you by email or SMS to go buy it on the Apple Store.
