About lettering, my experience. My last letter of two, getting back happily if not any spectacular news. But with additional comment. They were "now charging $15" per letter; MR. Jinks had kindly waived. Conjuring my guns, finances and the two marginally interesting returns, deciding... Not. None since, but IF at $15 now likely to seriously reconsider!
Story true, humor coincidental to times.
Best! Stay safe!
