How the Federal Prison Commissary Works:
** Inmate Accounts:** Funds sent to an inmate are deposited into a "bank-type account" (commissary account) for their use.
** Depositing Funds:** Friends and family can send money electronically (e.g., MoneyGram, Western Union) or via postal money orders.
** Purchasing Items:** Inmates use their account funds to buy items not regularly issued, such as snacks, toiletries, stamps, and some clothing.
