The discouraging part of this story is that the anonymous letter writer went public right away. To me that suggests more of a personal vendetta than any concern for the company, or they would have given the board some time to investigate and take action.

This could be a major opportunity for some retailers to improve customer loyalty and gain a competitive advantage. Let's see who takes advantage of it.
