InmateAid is a mail service to the inmate, not a direct line. You can write a letter with our service using a credit card. The coupon code is for offers that we run from time-to-time. Use the Contact Us link on the Home page with your email address and we will happily send you (or ANYONE) a discount coupon for your next letter.
