thanks for the great advice during out 15 minute premium consult! I forgot to ask you if I should be advertising all three formats: ebook, paper and hardcover. Chat GPT had advised me only to advertise the paperback since it was at a good price point $20 and the ebook is only 2.99 (little profit). However Amazon had lowered the price of the hardcover to $31 so it is also affordable? Anyway, would you recommend staying with all three or should I focus on the paperback. Thanks for your expertise!!
