I'm a Costco member and have not seen a posted no-weapons sign at the Ann Arbor store. Does anyone know where, exactly, the sign is posted?
Pretty sure it says something about members carrying weapons while in CostCo in your member packet. If I remember the wording is something along the lines of, "CostCo does not feel it necessary for members to carry firearms while in the store," or something like that.
Somebody correct me if I'm wrong because I've never had a CostCo membership and never plan on having one.
