Nowadays 32GB of RAM go for as little as 170$. Some mid-tier graphics cards cost much more than that.

They went for around 100$ during summer 2016, now the cheapest DDR4 is around 240$:

Wow, I didn't notice just how much fluctuation there has been in RAM prices. My Newegg order history shows I paid $65 for 16 GB of DDR3/1600 at the end of 2015. Now the exact same product is sold by Newegg for $122. Crazy!

I sometimes forget that people use Desktops or systems with ability to add extra RAM.
