Will the commissary be open on December 5th since it is a day of mourning for President Bush?

I expect it since normally it only closes every Monday plus Christmas and Thanksgiving. Your best bet is to call the Commissary directly. The phone # is on their website.

I hope so, it's not a holiday

The commissary will be open it's regular hours of operation.

Not sure, I only heard that mail will not be delivered. You might want to call before go there.
