Final answer:
A retailer is an organization that buys products to resell them to ultimate consumers, which can benefit all parties involved and contribute to waste reduction.
Step-by-step explanation:
Any organization that purchases products for the purpose of reselling them to ultimate consumers is a retailer. Retailers play a crucial role in the supply chain, acting as intermediaries between manufacturers and end-users.
When an organization like the Junkbuyers Company buys items for resale, they not only have a transaction that should be mutually beneficial for buyer and seller but also contribute to social welfare by reducing the volume of garbage, which leads to cost savings for households and municipalities handling waste disposal.
