People in general are creatures of habit. We get attached to buying the same products from the same brands over and over again. For example: what happens to our favorite brand of chips, cosmetics or electronics when the brand/product undergoes a change. A change in packaging or a change in brand name could have a big impact on the way consumers perceive the product/brand. Will the old trusty chips, that you once called your favorite, still be the same after a change?
