Taxe Percue is a sovcit thing. Yes, sovcits even try to get out of postage.

Thatβs my understanding from my various rabbit hole dives into this stuff. The percue prepaid envelope mentioned I believe is some kind of thing where they are levying the charge of postage against the millions of dollars that they believe is in a secret account. So they are probably invoking some obscure unrelated regulations and saying that the postage is covered through that.
