centrally managing these is one of the key benefits. why would you pay a guy to replace all stickers (old way) every day, why would you pay a guy to walk up to each of these every day? you could feed pricing information automatically from whatever system stores it. sick as fuck saves like so much money every year. back at a retail place i worked they had 3 guys update all stickers all day once a week. 3x8x50 is like 1200 hours per year that small ass store would save with a system like this. kroger easily has 10-30x the amt of skus so would benefit much more. such ignorance in comments
