> Seems like a VERY expensive way to keep prices up to date. The BOM cost on one of those little guys has to be north of $10 That's nothing, even after markup and multiplying it around all the shelves, consider the wages you have to pay for people to go around continuously re-stickering everything. I'm pretty sure it would pay off in under a month and reduce errors... freeing staff to do more useful things. What i'm sure will _not_ be paid off in a month is the cost of integrating it into existing pricing systems. However I think there is a more practical reason why it's not suited to most supermarkets: they are constantly moving things around due to different products coming and going and different parts shrinking and growing, so why bother with digital labels when you have to keep physically moving them anyway.
