There are many differences among low-order goods, middle-order goods and high-order goods. Low-order goods are products that are regularly bought and are cheap. For instance, a convenience market sells low-order goods such as sweet cakes, newspapers, juice, food, and lottery cards. Middle-order goods are time-to-time items that are bought but not as regularly as low-order goods. They are objects such as CD's, computers, or largest clothing items. These things are assumed some bit expensive. High-order stocks are the most costly things or have an inadequate store and are rarely bought. Some models of those would be mountain climbing supplies, specific magazines, live movies and multi-screen cinema shows. It is said that markets trading these goods require to have an origin community of tens of thousands.
