I used to work for a company that provided inventory services to retail stores. My recollection is that retailers often group together items of the same price and general character.
Having done vendor sales for 4 years previously, it's according to how the items are managed. If they are POS replenished (register keeps track of sales, communicates with a server and places an order with the distributor periodically) then each item will
have a specific item description that's usually download when that SKU is added. If the item is vendor manager (the beer salesman comes in, inventories back-stock and places an order) then the store manager may well group items into like SKUs to make price changes easier. Instead of doing 10 price changes - one for each flavor of juice, for instance, they will just do one price change since the store's markup/down will be the same. The vendor is responsible for keeping the dates kosher and the popular flavors/packages in stock.
Generally all a c-store manager cares about is the top 10 store-wide, top 2 or 3 per category and whatever they or home office is pushing to drive sales. In today's workforce, if you have a manager that can name those items and keep the money straight, you hold on for dear life.
