Many of my ebooks are free or 50% reduced for the month of July with Smashwords https://www.smashwords.com/profile/view/zhivago
How the Sale Works:
Readers browse the special catalog and search by discount levels, themes, and categories. After 11:59pm Pacific time on July 31, 2020, the catalog disappears.These discounts are exclusive to Smashwords and will not affect prices at other retailers.
There’s no need for authors or readers to remember coupon codes. Readers will receive the discount automatically by adding your book to their cart.
