how to buy food at the commissary

Inmates shop at the commissary normally once per week. You can place money on their boks using the various inmate money transfer companies. There is either a weekly or monthly maximum spend limit ($75/wk - $340/mo). You cannot normally shop for them unless the facility has an arrangement with a vendor that sells commissary baskets. You would have to check with the exact facility to see if they have a company for you to contact.
