Can the wives of the military shop there if the husband is deceased?

Yes

Thank u SO MUCH!!!! VERY INFORMATIVE

As long as they have military id.

As long as you have a DOD is you can get on post The Wives Can If They Have A Current DOD IS CARD

If you have an ID that will allow you on base you are able to shop at the NEX

I would think so, as long as they've got retiree benefits.
