Maybe your customer isn't trying to save money
Perhaps she wants to be heard instead.
Or find something better, or unique.
Or perhaps customer service, flexibility and speed are more important.
It might be that the way you treat your employees, or the side effects you create count for more than the price.
The interactions in the moment might be a higher priority.
Or it could even be the sense of fairplay and respect you bring (or don't bring) to the transaction.
Price is the last refuge for the businessperson without the imagination, heart and soul to dig a bit deeper.
