Name the channel of distribution that is used for selling goods through mail order.

The concept of distribution channels is central to understanding how goods move from producer to consumer. A zero-level or direct channel removes all intermediaries, meaning the manufacturer bears full responsibility for storage, promotion, and delivery. Mail order is a classic example because the producer communicates directly with the buyer through printed or digital catalogues, accepts orders by mail or phone, and ships goods directly. This is significant for exam purposes because students often confuse the number of intermediaries with the number of levels: a one-level channel has one intermediary (retailer), a two-level channel has two (wholesaler and retailer), and so on. The zero-level channel has none. A common exam trap is assuming that mail order involves a retailer because goods are sold to end consumers — but the defining feature is that no independent intermediary exists between producer and consumer. In real-world application, companies like Amazon (for its own products) and subscription box services use this model to capture higher margins, gather direct customer data, and maintain brand control. CBSE questions frequently ask students to identify the channel based on a scenario, so remember: if the producer reaches the consumer without a middleman, it is always a direct or zero-level channel.
