My biggest gripe about the commissary (besides the rather aggressive 90 year-old baggers who work only for tips) is the lack of generic products. I fully recognize that I am paying generic prices for name brand products for the most part, but not always. And I really appreciate the generic products that the commissary does carry.
I know the quality of commissaries vary greatly from post to post. I have been in some on large posts, that are nicer than any store out in town, but we have mostly been stationed at smaller posts with older, smaller facilities.
Do you use the commissary? Does it save you money? Does your commissary have very aggressive elderly baggers? Or are the hassles involved more than you can handle?
