I like how easy it is to track my shipments, including where they are in real time! It makes me feel secure knowing that if we have something shipped or picked up by someone outside of our control then PTT will tell us exactly what happened so there's no guesswork involved (or potential loss!). There isn't anything i dislike about predictive transport tracking. If you're looking for affordable shipping costs with ease-of-use this service definitely fits your needs perfectly. We use PTT when sending packages out from one location to another via USPS Priority Mail Service. The benefits include quick delivery times along with peace of mind as far as shipment status/location goes which really helps reduce stress levels since everyone wants their package quickly but not missing deadlines because of delayed deliveries.
