Why would you need a robot running around the store? When I take a package of dorritos to the register the scanner determines the product and price. Should they not be able to use that info to detemine that there is one less bag on the shelf?

that will only determine that there is "at least" one bag off the shelf. So Poopy the Robot, or whatever, will have to restock at least one, but then count anyway.

eh....I don't know.

In a perfect world. But large, changing numbers requires Calculus to keep track. Then, mis-pricing or changing prices, misplacement, and inventory shrinkage (theft) requires an inventory to reconcile. So this is really good, taking inventory is such a pain.
