Distribution Arrangement

Intensive

It's a product distribution where the company sells as many outlets as possible, so the consumers can find the product everywhere they go. The advantage of intensive distribution is that it makes customers remember and eventually buy the product, because they come across the product frequently. Products that are distributed in this way are the ones that you use everyday like a toothpaste. The original shop for toothpastes is a drug store, but you can buy them in grocery stores and supermarkets too.

Selective

This retail strategy involves making products that are available only in certain markets. It's the opposite of intensive distribution. Basically, the benefits of selective distribution are that a retailer is able to control his product, which means he can limit distribution of his products to specific geographical areas. This creates a "good image" of products, because it looks like they are special in some way as you can't get them everywhere. An example of this is luxury goods, or goods that are expensive because of their brand. These products are just for one group of people (upper class) so not everybody can afford, and are not sold everywhere.

Exclusive

It's a distribution where distributors and suppliers make an agreement that allows only some named distributors to sell a product. A positive thing about exclusive distribution is that a supplier has once again a control of how distributors display the product. It gives  a competitive advantage to retailers too because they can pay for displaying the product in a particular section of the store. For example, Nike and Adidas use this technique all the time.

Integrated

Integrated means combining or putting this together. Therefore, integrated distribution is a distribution that puts different types in one effective group. Advantage is that a supplier has a close relationship with other channel members. An example is the Carnegie Steel Company where the company controls not only the mills where the steel is made but also the mines where the iron is extracted. 

When you are choosing a distribution channel it is important to realize that it is not short term. It also requires careful choosing among and between distributors, direct marketing, retailers and sale force. Distribution is one of the two main roles of marketing., therefore it definitely requires strong strategic thinking.
