Think about who is sending you the message that this grocery store is a low price leader or that these items have the lowest price, the grocery store. It takes your brain seeing a message 7 times or less for it to be ingrained, with out you even noticing what is happening. So of course, grocery stores will put big signs up that they are “Low price leaders” have the “Lowest prices” etc. Become an educated shopper so you know the prices and can make good judgements. Also, know that a stores’ low price promise may just be that it is the lowest at that store and not compared to other stores in the area.
