Shopping is considered a leisure activity of psychological interest. Shopping engages selection and purchase."Window shopping" is an American/English phrase meaning to seem into glass windows of a shop for amusement and imagine purchasing items without
actually purchasing, possibly just to pass the time among other activities, or planning a purchase.Shops are divided into numerous categories of stores
which sell a selected set of goods or services.Many stores are part of a chain: a number of similar shops with the same name selling the same products in
dissimilar locations. The shops may be owned by one company, or there may be a franchising corporation that has franchising agreements with the shop
owners. Several shops sell second-hand goods. Often the public can also sell goods to such shops. In other cases, particularly in the case of a nonprofit shop, the
public contribute goods to the shop to be sold. In give away shops goods can be in use for free. In Antique shops the public can discover goods that are
older and unique.
