I recently E Mailed KMart asking about their corporate policy regarding non licensed Open carry since Michigan law of course requires the permission of the "owner or the agent of the owner" when it's a store that sells liquor, and I thought you might be interested in the response, it looks like KMart does not have a problem with it.
Dear Valued Customer,
Thank you for your recent correspondence. We are always interested in
hearing from our customers, and regret it was this type of situation
that prompted you to contact us.
Our corporate policy regarding customers who openly carry firearms on
our store premises is that as long as the law of the state, in which our
store is located, legally permits the open carrying of firearms (i.e.
carrying a firearm on one's person in plain sight), customers will be
permitted to openly carry firearms within our stores.
By sharing your concerns, you have enabled us to provide feedback to the
appropriate person. Truly, your remarks provide forthright feedback
that will enable Sears to achieve excellence in everything we do.
Once again, thank you for contacting us.
Sincerely,
Jennifer G.,
Retail Customer Care
Sears Holdings Corporation
