What the frell is CLV !?!?

If you don't know what a customer is worth, you're inefficient. You should be thinking like this:









Average Order Profit
         x
Number of orders per year
         x
Average customer length (years)

         =

Customer Lifetime Value (CLV)


CLVs are important if you are selling anything.

...
CLV is not (here) a reference to how fast CDs work.
