Well, I hope the Betty White stamp works out ok.
I was using my Ruth Bader Ginsburg stamps to pay bills last fall and NONE of them reached the bill collector.
I can only assume that some MAGA person in one of the sorting centers they passed through made sure those envelopes were destroyed.
Luckily for me, the places they were supposed to go contacted me and I then rushed to pay those bills online before my insurance was cancelled and other problems with the other bills. Had to call my bank to stop payment on the missing checks.
I've not used her stamps again and probably won't because the Post Office hires all sorts of people and some of them .....
