Sure they are eInk? On Carrefour here they have had plain old LCD ones for ages now. It looks like e-ink, but on close inspection it is definitely not (e.g. mirrorish background color). Polarized glasses also help detection :)

And that is what I do agree e-Ink is overrated. People have trouble distinguishing it from reflective LCDs (remember the Pebble).

Can confirm that Japanese supermarket is also full of small 2x1 inch eInk screens for prices (multicolor even).

Here at Kohl's the price signage is e-ink.
