sales volume and sales value

  • hab hier einen text:
    The market size is measured by the total volume or value of all sales in the market. The Sales volume is measured in terms of the number of goods sold or services rendered, while the sales value measures the total amount spent by customers on the volume of goods sold.

    sales volume versteh ich ja... aber unter dem sales value kann ich mir nix vorstellen... weiß jemand rat?

    thnx vorab!
