When coupled with commercial discounts, not only are the savings extensive but so are the shipping options. It's a seemingly great problem to have until you're faced with selecting which USPS Priority Mail service to use.
Overview of USPS Priority Mail service options:
To start with the basics, USPS Priority Mail rates comes in four flavors:
- Flat Rate packages (boxes and envelopes)
- Regional Rate boxes
Most shippers are very familiar with weight-based and Flat Rate package options. However, there are many situations in which Regional Rate boxes and dimensional-based rates will yield lower rates. In the end, it all comes down to a few key factors:
- Weight of the package
- Size of the product, which determines the size of the package
- Distance the shipment has to travel, which determines the Zone of the shipment
