Thursday, October 3, 2013, news came out that in the light of military commissary shutdowns, Sam's Clubs near military bases will welcome all military, active or retired, and their families, to shop in their stores without a membership. 

Sam's club decided to waive club fees until the government re-opens the commissaries. 

You will need to check with the Sam's Club nearest your military base to see if they are honoring this generous offer.
