USPS online label printing question

[dude8604]

I just printed out a Priority mail label from USPS's website. I chose the option to print a label with postage. I'm confused about how I will be charged for it. The label I printed says "U.S. Postage Required" on the top. Does that mean that I need to buy shipping separately (or use stamps?)? Please help me.

Umm, if it says postage required, I think you still need to pay for it, otherwise it'd have a weight and price on there.

Is there a way to pay online?
