Are customer satisfaction and customer value interdependent or mutually exclusive?

     For a customer to be satisfied the product has to have everything the customer is expecting.  Customer value is what the customer is willing to give for what the product has to offer.  Customer value is defined in our textbook (MKTG) as “the relationship between benefits and the sacrifice necessary to obtain those benefits.” Customer satisfaction is defined by our textbook as “customers’ evaluation of a good or service in terms of whether it has meet there needs and expectations.” I think that customer satisfaction and value are on the page.  If the customer is not satisfied with the product then the customer value is going to go down.  This makes for a interdependent relationship with one and other. 

What do you think, are customer satisfaction and customer value interdependent or mutually exclusive?
