Retail is all about selling products to customers.
Retailers have to buy, too, from wholesalers and suppliers. Retailers range from those who sell everyday items (such as food) to occasional purchases (such as diamond jewellery and cars). Shops themselves vary from tiny specialist outlets to giant superstores and department stores that seem to sell almost everything. Trades stores such as builders’ merchants or food suppliers sell to businesses.
Not all retail jobs are on the shop floor. Each large store has ‘backroom’ staff dealing with finance, human resources (HR) and admin.
