CNBC Supermarkets Inc. - Secrets Revealed

Why are they arranged the way they are?  Did you know that some stores use heat maps to track which aisles you walk down — and which ones you don't?  Or that they put the milk at the end of the aisle so you're forced to pass a hundred other items on your way to get it? It's all done to gain an edge in a cutthroat business built on razor-thin margins.
