Final answer:
Channels of distribution primarily benefit businesses by getting their products to consumers more efficiently, often leading to a broader selection of goods at lower prices for consumers, thereby helping businesses to maintain or improve their profitability.
Step-by-step explanation:
The question addresses the benefits to businesses from having efficient channels of distribution. One of the key benefits is getting their products to consumers more efficiently, which can lead to increased productivity and availability of goods. This efficiency can often result in a larger variety of goods at lower prices for consumers, and can help businesses to corner the market, keeping their prices competitive, and maintaining or increasing their profit margins. However, channels of distribution do not inherently guarantee annual profit raises or the avoidance of all channel tasks.
