Parcel Select Ground® is the cheapest way to ship big packages

Parcel Select® is a Commercial service that isn’t available at the Post Office. The comparable Retail service is called Retail Ground® and it costs up to 39% more than Parcel Select Ground®. Pirate Ship passes through the cheapest rates available for Parcel Select Ground®.

The maximum size for Parcel Select Ground® is a combined length and girth of 130" inches, which means adding together the dimensions of the longest side of the package plus the distance around the thickest part.

The maximum weight for Parcel Select Ground® is 70 pounds.

If you’re shipping a large, light box, Parcel Select® is cheaper than Priority Mail® because it will not get charged for dimensional-weight pricing like Priority Mail® does. With Parcel Select® your package will be rated off the actual weight, no matter how large the package is.

But watch out for balloon rate pricing if you're shipping a really big package with Parcel Select®. If your package's Length (longest side) + Girth (Width * 2 + Height * 2) is between 84" and 108", for all zones you'll be charged the 20-pound rate instead of the actual weight's rate.
