USPS Shipping Rates / Test printing labels ?

[Julia_NY]

I've read several posts on this forum that Paypal may have incorrect pricing for shipping via USPS.

Is there a place here on Paypal that I can review the options (ie flat rate, first class, regional rates)for shipping via USPS and the rates posted?

Also is there a test area to try out a sample to see if a shipping label is printing correctly before I actually do one?

Thank you
