It's literally your commissary - have you talked to the manager about changing hours?
We were told there wouldn't be a deli put in at NAS Whiting because , and I quote "It's not what the retirees want."
So much for it being our commissary :-(
I suppose I haven't seen a commissary yet that didn't offer a decent price on most of its products. In general, if you shop around the outside of the commissary, you'll find some of your best deals. That includes meats, dairy, eggs, and sometimes produce. Typically, my wife and I save around $40-50 per month by just shopping on those type of items alone. If you shop the sales throughout the rest of the store, you'll find some pretty decent prices there as well, and has already been mentioned, you're paying generic/store brand prices on the name brand items.
Thus far, the commissary has proven to be a great asset for a family on a tight budget (mine). Do we still shop in town? Occasionally, when the local grocery store has a better sale going on for specific items. The funny thing is, when we go shopping there on the weekends, they have local high school groups bagging there for, you guessed it, tips as a fundraiser. So, don't think that the commissary is the only place around that expects you to tip your baggers. Furthermore, you don't have to tip the bagger if you don't want to. If you tried to bag your own groceries, and they wouldn't let you. . .to hell with them. They just told you that they would rather work for free.
