Explanation

Distribution channels move goods from producer to consumer. Direct: producer sells directly (farm stands, factory outlets). Indirect: involves intermediaries (wholesalers, retailers).

Common chains: Producer → Consumer (direct), Producer → Retailer → Consumer, Producer → Wholesaler → Retailer → Consumer. Each intermediary adds cost but provides valuable services.

Wholesalers buy in bulk and break into smaller quantities. Retailers reach final consumers. Choice depends on product type, market coverage needed, and cost considerations.
