retail sales Vs direct sales?????

If you are asking definition of both of these then you can see below and if you are asking which is better then it depends on the products or businesses you are in.

Direct Selling is a retail channel for the distribution of goods and services. At a basic level it may be defined as marketing and selling products, direct to consumers away from a fixed retail location.

Retailing consists of the sale of goods or merchandise from a fixed location, such as a department store or kiosk, or by post, in small or individual lots for direct consumption by the purchaser.
