Could also be algorithmic pricing, though.
Try searching on amazon for some random, unremarkable video card, sometime. Then, switch the order of the results to "Price: highest first". I just did that with the RX 550, which launched in 2018 with a MSRP of $79.
Here, I found one listed for $1,020.45!

That's the most extreme example, but there are like a dozen models listed for over $500. It makes no actual sense to price a RX 550 that high. It's an old card that's not particularly in demand. Even during the crypto boom, you
still probably wouldn't have seen them selling for that much!
Here's one resource that delves into a little depth on the algorithms Amazon uses.
They also mention Amazon's API, and here's where I think some of the most egregious examples might occur. I suspect these are the result of 3rd party plugins, but it's not something I have any direct knowledge about. When it comes to items sold by Amazon, itself, they typically do not have runaway issues like I tend to see with marketplace sellers. I guess that's what makes this cooler a somewhat unique example.
