Worth knowing in Inland Empire
The buildings here are large and the ordering patterns predictable: steady weekly use with a sharp rise from late summer into the holidays. Many tenants are 3PLs serving several brands, each with its own carton list. Dock appointments are tight and drivers wait in queues, so a delivery booked for a set window, with the count and sizes clearly labelled per pallet, makes receiving easier. We quote those details along with the boxes.
We quote delivery to every ZIP in both counties of the Inland Empire (Riverside-San Bernardino-Ontario) metro area, Riverside and San Bernardino, not only the warehouse districts.
