They were using them the other day (since your post) in Appleton, Wisconsin, Outagamie county.

I was physically in the store listening with an earphone to my scanner so I know it was them. So ah ... how do you report them,
if it's true? If a license expires don't they have a grace period? Or were they never licensed? And is there a national or state license that sams covers all there stores with? When I have time I'll check it out I guess. I could probably even see if they're still using them the next few days.
