I don’t know why people are getting worked up over this. Don’t want to get a letter or think they are worthless? Then don’t. No one is saying you have to buy one. Buyer beware applies to everything whether there is a letter or not. You buy the gun not the story. Anything extra is gravy.
I just got 3 letters. They don’t say a lot. But I know where it started it’s work and that makes it ok with me. It’s because I look at it as history and part of the story. Some have a short story. Some have a novel And some never care to read the book. Life’s all about choices

Boils down to buyer beware and don’t worry what other people do
