I'm probably not up to speed on this subject but my wife likes to shop at Wal-mart and Sam's Club. I've told her it probably isn't a good idea since they are non-union. Anyway, yesterday she came home hotter than a $2 pistol. It seems Sam's & Wal-Mart pharmacies will not honor our insurance because it is Union affiliated. Yet another reason to boycott Wal-Mart.
