answer:Chainstore would most typically carry a wide assortment of goods, including organic products. Prices at chainstores would tend to be less expensive than independent grocers as they have the economies of scale working for them. Chain supermarket is what I frequent for food and groceries. Independent grocers are great for those one or two things that you need in a jiffy, no hunting for an item up and down the aisles, no long lines at the checkout, my neighborhood grocer even has a drive-thru window. However, selection may be limited and prices a little more marked up, but it’s convenient for picking up just a jug of milk, or a carton of OJ or loaf of bread. Co-op food markets are specialty stores that cater to a special crowd. Needless to say, I am not part of the special crowd.
