I was in Walmart one day looking at items on a shelf when I noticed that a tiny light on one of the price sign's upper left corner was flashing red. Soon after, a guy came, grabbed the item above it and the flashing stopped.
I asked him if he made the thing blink. He said yes. He said that he was a shopper who shopped for other people. His customer selects what they want on an app, and he's able to use that app to locate the exact items by using the binky feature.
How cool izddat!!??
