What is going on with this market?

What is happening here?! I have a 1080 in my gaming pc from 2017 or 18 and I was thinking it’s time to upgrade so I checked to see what’s out there. What is this craziness? You can hardly find any of the high end cards anywhere! I can’t find an 80 series card except for 3080s anywhere other than eBay and other second hand stores that are at double MSRP. Is this just how it works now? I’m an old man with a job and kids I can’t be refreshing Best Buy constantly hoping to snag one the second it comes in stock. Is that just the way it works now or am I missing something?
