Every week on Facebook, in the group "Sanctuary of Heroes Marketplace" we post books for pre-sale, you can order any you like and won't be billed until they release. We also post all the new releases in a post on Monday or Tuesday that allows you to claim the new releases right from your app.
If you prefer the regular method, we will post Final Order Cut Off each week of books that releases in 3 weeks. Those books must be ordered by the end of the week it was posted, so get your orders in early. As always if you have questions you can call 360-939-1530 or email firstname.lastname@example.org
