I will gladly pay postage to anyone that got mine and had to pay. This is what I was told: I took mine to the post office and she weighed and put it through their little slot card and said they were fine at 45 cents in the US, I did not put the stamps on, she stamped them. She said the directive from the PO that they get is that it is strickly a judgment call anymore. If it comes stamped from another PO it has been okayed by them and that no due postage is ever charged. If you, meaning us, puts a regular stamp on them and just mails them, then it is the judgment call on the receiving PO as the whether postage is due or not. This lady is the postmaster here and says she hates it because no 2 people can ever be the same every single time. Hope this makes sense of what I'm trying to say, anyway I will send the extra postage if you just let me know.
