All new to me. Helping elderly neighbor whose grandson is in Perry County Prison of PA. She has me deposit $200/month in his prison account. Is this typical and reasonable? (She has taken out a loan at 27% annual interest to cover expenses.)

The $200 per month is reasonable to cover things like telephone calls and commissary. The very troubling part is the 27% loan - which we would strongly suggest NOT doing. Inmates can live without the extra money coming in. It is definitely nice to have while you're doing time, but it is not mandatory.
