How do I pay for the postage fees?

Postage: If utilizing our mailing permit, postage MUST be received 48 hours in advance of the mailing date. Estimated postage payments will suffice until the actual postage is determined. Any difference in postage will be applied to the service invoice. If using your permit, please be advised that the account MUST contain sufficient funds to cover the postage costs of the mailing.

Terms: Prepayment on ALL services is required on the first order. For all orders thereafter, "15-day terms" will be granted for services upon acceptance of a credit application.
