USPS Priority Mail

FedEx or UPS Ground will be less expensive. Ground service will be slower that Priority Mail. USPS Priority Mail across the country will be handled less since the package will likely have to travel via air to make the 2-3 day delivery guarantee.

Other than that, there's little difference, IMO.

Every two weeks or so, there should be an automatic new "Bitch About Shipping Companies" thread so everyone can kvetch.

One thing is constant...everyone has their tales to tell, and no shipping service is perfect.

Depending on what time of the year it is & how far away the destination determines whether the package will fly or not via Priority. There is no guarantee for 2-3 day delivery. They will *try* and deliver in 2 or 3 days.

That's true. However, my experience has been that 100% of the items I have mailed via USPS Priority Mail, including coast-to-coast parcels, have been delivered in 2-3 days. At this point, that's probably close to 100 Priority Mail transactions.

The video was so revealing, and disturbing, that it became the basis of a number of lawsuits against the USPS for the intentional damage caused to the Priority Mail class of shipping through mishandling.

"Intentional damage" lawsuits?

Those will be quickly laughed out of court, if they even actually exist.
