Expanded Distribution (KDP).

Expanded Distribution makes a KDP paperback available to the distributors that bookstores, libraries and academic buyers order from, in the United States and the United Kingdom (KDP Expanded Distribution). Enrolling is free and it is a checkbox on the pricing screen, but the royalty drops to 40% of list price minus printing cost, which on Amazon's own worked example turns the $4.00 a $15 book earns on Amazon into $1.00 (KDP paperback royalty). Hardcovers are not eligible, and the distributors also refuse journals, notebooks, planners, coloring books, public domain content and a long published list of saturated subjects. Nothing about it is quick: Amazon says up to eight weeks after acceptance before booksellers and libraries can order, and up to eight weeks again for a price or content change to reach them. Enrolment guarantees nothing either, because distributors decide whether to list and booksellers decide whether to order, and Amazon will not tell you which ones did.
