I'm starting to see tiny e-ink displays sticking out of shelves with prices on them. Mostly sale items..  Not a lot, but its starting. 

Kohls has been using LCD on their shelves for a while now . Ahead of the curve.

I guess large LCDs are changing things quite a bit. 

I noticed that the slots and poker machines are all basically using curved LCDs in Portrait mode, now. They're just really big Samsung CHG-90 curved gaming LCDs.

I've given the example before - until the mid 90s local grocers were
hand inking their "Weekly specials" on butcher paper. Now, they use
DTP and large format printers to print out slick, high gloss specials

That's so OLD FASHIONED.

Large format printers for in-store display copy was a thing for a very brief period of time.

Now they just put big screens up behind the counters. So there's another place where hardcopy is dead.
