Below is our Host Rewards chart. Free and half price book rewards always start at $100 in total party sales and increase from there. At $100, you would get $10 in free books and $25 in half price books. For every additional $25 in sales, free books increases by $5 and for every additional $100 in sales, half price books increase by $25. Once you reach $300 in sales and have at least one booking (someone who wants to host their own party) from your party, you earn the extra incentives!
