I went into my local Wal-Mart (not a Super Wal-Mart) and noticed the area where they used to stock Williams pucks was empty. The sticker tab was also missing. They usually had about 20 pucks at any given time. I could not find any clerks to ask if they were discontinued but I am assuming this. Also noticed the Personna cart section was getting very thin. There used to be many Personna Cart replacements but they are disappearing. Has anyone noticed if there Williams pucks are becoming extinct?
