What does reseller mean?
A company that purchases services or goods for resale rather than consumption. In ecommerce, this can often apply to an affiliate marketer. Retailers are considered resellers, as they resell goods to end consumers. Wholesalers are also considered resellers as they resell the goods they purchase to retailers.
A reseller will buy goods for resale and make a profit, a retailer purchasing goods from a manufacturer that he will then sell on to his customer for a marked up price. The reselling chain will see a mark up in price from manufacturer to retailer and to the client, each person in the chain making a profit from the resale of the goods. Resellers might simply mark up the goods they resell, or they could add value through combining related products or repackaging.
