Retailing and wholesaling are crucial links in the distribution chain, connecting manufacturers to consumers. Retailers sell directly to end users through various channels, while wholesalers sell in bulk to other businesses. Both add value through functions like inventory management and providing product assortments. The retail landscape has evolved with e-commerce and omnichannel strategies. Brick-and-mortar stores now compete with online retailers, leading to innovative approaches like experiential retail and pop-up shops. Wholesalers face challenges from retailer consolidation and manufacturers selling directly to consumers.
