Book Launch Blueprint Cost? (Ballpark)

Hi, does anyone know around how much the Book Launch Blueprint course costs? I want to do a course, conference, or coaching this year and I’m trying to figure out what my best option is in terms of content and cost. I saw the schedule from last year but not the cost. I know it might be a little different from year to year but I was hoping someone might be able to give me a ball park estimate or even just what it cost last year.
