Because you can never do enough advertising (or spend enough money on it...), a few days ago I put together a mailer that I'm sending out to a bunch of shops - some of the ones that didn't get the preview books in the mail. I included the previous advertisement that worked its way into the Previews catalogue as well as a pandering letter to comic book shop owners everywhere.
Will this work? Who knows. But the post office is very happy with me lately, I'll say that.
