It’s in their membership agreement that nobody reads. I wonder what Sam’s policy is.
At Costco, we don’t believe it’s necessary to bring firearms into our warehouses, except in the case of authorized law enforcement officers. For the protection of all our members and employees, we feel this is a reasonable and prudent precaution to ensure a pleasant shopping experience and safe workplace. Our policy is meant to protect our members and employees in all warehouses around the world. This isn’t a new policy, and we don’t customize this policy for each city/county/state/country where we do business. Our primary goal at Costco Wholesale is to keep our members happy. If you believe that our policy restricting members from bringing firearms into our warehouses is unfair or excessively burdensome, or you cannot agree to abide by this policy, Costco will promptly refund your annual membership fee upon request. Thank you for your understanding.
