mymagstore ships to prisons every day, but there are restictions and rules.

 -  Adult magazines are generally not allowed.

 -  Magazines depicting violence or gangs are often rejected.

 -  Men's magazines, such as Maxim or FHM, are sometimes rejected
    because of nudity.

 -  The number of magazines allowed at one time is usually limited.
     It seems three is a safe number, but check with your institution.

 -  Many states have requirements that magazines, books, and newspapers
    come directly from the publisher, but this is interpreted differently
    by each state, each prison, and each mail-room employee.  Several
    states have consent decrees that treat internet providers like ourselves
    the same as Barnes & Noble or Borders, but we still sometimes get rejected
    as not being "directly from the publisher".  We have shipped to the
    same inmate in the same facility several times, then a shipment will
    be rejected as not from the publisher.  Then the next shipment goes
    through with no problem.

Sometimes the magazines just don't get through and either disappear or get returned to us unopened.  We will give you a tracking number from the USPS so you can follow the shipment, but if the prison rejects all or part of the order, we assume no responsibility, and you must bear the cost.
