"Markets consist of buyers, and buyers differ in one or more ways. They may differ in their wants, resources, locations, buying attitudes, and buying practices."(Kotler, Marketing An Introduction, ch. 6 pg. 167) The buying practices of people with hands will greatly differ from those people who don't have hands or cant use their hands. for example people with hands wont need to practice doing simple things such as opening a can or opening a meat package. Also people with no use of their hands will need special cooking utensils, such a toe knives and ankle blenders. With the cook book Eating With Your Face, Cooking With Your Sole you can recieve a list of different cooking utensils for the feet. so of course people who have no hands will have different wants and resources, along with different buying practices.
