.ar "Mailing Releases by Airmail" Our policy is to mail release tapes and associated documentation by regular (third class) mail. If you wish to receive any of this material by air mail please make prior arrangements with us for your payment of the airmail postage, e.g. send us your Federal Express Number, an account number to which we can charge, indicate that you would like it sent C.O.D. (not applicable to customers located in other countries), prepay us, or indicate that you would like us to bill you (there will be a $5.00 billing charge). For those of you wishing to prepay us, the release tape, conversion guide, subsystem manager's guide and the cover letter weigh approximately 3 pounds (1.3 Kg).
