I've been writing an inmate in a US prison for the past few years. He was in a maximum security prison, and sending books from Amazon or Book Depository was never a problem.
He was recently transferred to a medium security prison and says the prison won't accept books that are shipped in cardboard boxes or bubble wrap, and they will be sent back. I have spoken to both Amazon and Book Depository and they say they cannot chnage the shipping method, therefore they can't help. I don't live in the US so I can't just have them shippied to my address and then mail them myself.
Do you have any ideas where I could buy from that will ship the books directly and use my choice of packaging, like a large paper envelope?
