What can an inmate buy in the commissary?

The commissary lists generally include typical personal hygiene items you'd find at a drug store. The facility provides the bare minimum but inmates can "upgrade" some of these essentials. They also sell foods and snacks. There are items that are sold that act as the currency for the jail. Packs of tuna, chicken, salmon and beef are used for bartering between inmates for services between themselves. They also sell candy, chips and other junk food. There is a limit that can be spent each week or month.
