Establishing a store and selling your products is great, that is called a direct distribution strategy. However, to increase reach, businesses could also engage in an indirect distribution strategy and sell their products through retailers or other middlemen. Engaging in both at the same time is called a dual distribution strategy.
For example…
Take M&M’s stores, they have a few retail locations around the world, where customers can walk into the shop, buy delicious chocolate products and other goodies and walk out. However, they also sell their products through retailers like supermarkets, department stores and even gas stations. As such, M&M is using a dual distribution strategy.
