New devices are available for < $200.
Used or displays are in the $50--$100 range, quite possibly less.
Pricing depends on size, resolution, greyscale ranges (1--16 bits, 4 is common for many smaller isplays), and refresh rates.
I was expecting 2022 to have $10 e-ink displays I could use to replace the 2x16 and 4x16 LCD screens in my Arduino projects.
But nope, anything over 2" is tens of dollars still - as it was 10 years ago.

For a 4x16 LCD, the 2" displays are probably most comparable, and are in the same price-range as the equivalent LCD (about $8--$12).

2" e-ink multi-colour displays with far higher resolution ... are about $20.

I'm no fan of E-ink's patent monopoly, but you're being ever so slightly disingenous / unreasonable here.
I would be in DIY heaven, if one could buy such foil by the meter, for a sensible price. Just imagine, what kind of displays for DIY devices one could accomplish!
