Well, it does seem like an odd thing to sell your customer on, doesn&#x27;t it?  If you wanted to do some home renovations and somebody told you they had no idea how much it would cost to do until they started working on it, you might be uncomfortable.  There are scenarios where this isn&#x27;t an issue but I wonder if it&#x27;s as broadly applicable as we&#x27;ve made it out to be.
