Has your favorite item disappeared from the supermarket's shelf? There are four main reasons for that. 1) The product was discontinued by the manufacturer. 2) The manufacturer went out of business. 3) The manufacturer/distributor had declined to pay for shelf space. Many stores charge products for shelf space, sometimes the manufacturer decides they want too much. 4) The store is trying to get you to switch brands. This is becoming more common. A product will disappear completely, or for a few weeks. The supermarket is using a lack of choice as a way to push consumers into buying the store brand or other higher profit alternative.
