The Cheapest Ways to Ship With USPS®

A few simple and basic rules of thumb for knowing about the most affordable ways to transport. If your parcel weighs:

• 15.9 ounces or lower than that, then utilizing your parceling with the high-quality package would be the most affordable, always.

• More than 1lb, but it is compatible with envelopes or Flat Rate boxes. These are the most affordable options.  

• You can’t keep more than 1lb and into those; using smaller boxes is most affordable. In this way, you can qualify for the Priority Mail Cubic.

• Medium and Large boxes of Flat Rate will be a good option if the weight is over 20lbs. However, Rate Boxes that are regional may not be a great choice.

An advantage of Priority Mail Cubic is that you will be able to utilize your own parceling.
