USPS actually lowered their shipping costs, using Click & Ship.
They added the new service, Ground Advantage. It's cheaper than 1st Class and includes insurance up to $100. I find the shipping speed equal to 1st Class or Priority. Lately, Priority seems to offer no speed benefit. I can ship a pipe, in a small box, for just under $4 insured. In the past few years, via USPS 1st Class, that would have cost around $7-$8. I use Priority for pipes over $200 in value, and buy the insurance. I'm not sure how what the max value Ground Advantage would provide.
These costs and this service may only be be available via Click & Ship. I can do the labels in my home, its the way to go.
I've shipped out around 300 or so pipes in the past 10 years, using USPS, so I've seen it all.
