are e-Paper displays really still that expensive to manufacture or is this a monopoly thing?

@noiob Our local budget grocery store (literally called "No Frills") switched entirely to small e-ink displays for all their price displays. So I gather they aren't THAT expensive at the right volume.

@hache well, I know the small ones are dirt cheap, I have one that plugs into a Raspberry Pi, but I want one I can read books on

@hache like, I love the small price displays, they're better than they need to be and really useful for stores, but they're a) tiny and b) slow, especially the two-color ones
