shipping a manifold

I don't know what they use and presume it's volume. I just like the prices to pass along to customers and the fact it's actually enjoyable to ship again.
Just going online saves you money

I dont go into the post office anymore
I qoute the whole thing online, print my own label and when Newman comes by the next day, he picks it up for me

The biggest gripe I had with USPS before this is that thier website would always quote lower then thier store front charged

This way, that won't bite me in the rear anymore
