Product specifications, availability, software features, carrier programs, postal standards, and prices can change. ADDCO uses current manufacturer and USPS information as a starting point, then confirms the actual model, configuration, mailpiece, carrier account, quote, and effective date before a purchase decision. Public complaint pages are used only to identify questions buyers should resolve in writing; customer allegations are not presented as proven facts.
