It is nice to see that you are proactive in trying to get them to clean up their act. I wish you good luck with that, They have always assured me that they meet the "minimum" standards of animal care.
It seems like as long as they sell animals and don't get too much bad press then they are fine with their animal care.

The few good stores I have seen have more to do with the store management and the people they hire than the company itself.
