Used equipment brokers have emerged to purchase and resell old or used items as their value has depreciated compared to new items. They must be mobile to meet customers located far from their offices, so they own cars and trucks. Many have physical offices where customers can visit to negotiate purchases, while others operate online by posting items for sale and requests to purchase items. As they deal in used goods, brokers must be persuasive and good bargainers to attract buyers and complete sales.
