Another user in the BlueSky thread showed a photo that appears to be a Best Buy case of RAM, showing a 32GB set of two DDR5 DIMMs going for over $400 USD, a 64GB kit for over $900.
If I hit Google Shopping, which indexes a ton of retailer sites, I can find 2x16GB DDR5 DIMMs for far less than that at various retailers that haven't jacked up prices yet.

Kingston Fury DDR5 32GB (2x16GB) 5600MHz CL40 RAM KF556C40BBK2-32
$100.00
They say that they have two in stock.
