BookBub
Best for: Curated daily deals with editorial selection
BookBub is the 800-pound gorilla of free ebook discovery. With over 15 million subscribers across all genres (Historical Fiction alone has 2+ million subscribers), it's the largest platform in this space. Their editorial team hand-picks deals, which means quality is generally high—but acceptance rates are only 10-20%.
Pros
- Excellent genre categorization with author follow notifications
- High-quality editorial curation
- Clean, well-designed emails with personalized recommendations
- Multi-retailer support (Amazon, Apple Books, Kobo, B&N)
Cons
- No price alerts for specific books you want
- Authors must pay $50-$1,000+ for featured placement
- Strict acceptance requirements (50-100+ reviews, professional cover)
eReaderIQ
Best for: Price tracking and alerts for specific books
eReaderIQ takes a different approach—instead of browsing deals, you add books you want to track and get notified when prices drop. They also offer a Chrome extension that injects price history directly into Amazon pages.
Pros
- Excellent price tracking with historical price charts
- Chrome extension for easy tracking from Amazon
- Import your Amazon wishlist directly
- Track by author—get notified when any of their books drop
Cons
- Not great for discovering new books
- Requires you to know what you want first
- Interface feels dated
Freebooksy & Bargain Booksy
Best for: Genre-specific newsletters with indie book focus
Freebooksy (for free books) and its sister site Bargain Booksy (for $0.99-$4.99 deals) focus on genre-specific newsletters. With over 317,000 registered users across 17 genres, they're a solid choice for indie book lovers.
Pros
- Highly targeted genre newsletters
- Great for indie book discovery
- More affordable for authors than BookBub ($20-$85)
Cons
- Author-paid promotions (quality varies)
- No website browsing—email only
- Deals expire quickly
Book Deal Finder
Best for: Real-time verified deals with quality ratings

Info
Pros
