Your scheduled promotion date is not always the end of reader discovery.
The Fussy Librarian personalizes recommendations, and eligible books may receive additional exposure to interested readers after their originally scheduled appearance.
Readers may also open newsletters later or return to books they previously noticed.
For that reason, some promotions continue receiving clicks after Day 1. If your ebook is free or discounted for several days, keeping the promotional price active can give those later readers an opportunity to take advantage of the offer.
