Just becuase I want to through my recent experience in here and beat a dead horse even further. :) I had a nice chat with P.O. lady the other day, who I actually didn't think much of until recently. She told me that Non-Machinable has gone down from .22 cents(i think) to .15 cents. We also spoke about rates for PWE, and if I understood her correctly, it's .55 Cents for a PWE 1 to under 2 onces. and .70 cents for 2+ ounces.
meaning that a non machinable stamping for a typical 1-2 once PWE cost me .70 cents. and the same thing but 2 onces was .80 cents.
In the US that is.
