How We Verify Free Kindle Books
Our commitment to accuracy means you'll never waste time clicking on expired deals. Here's exactly how we verify every book.
Why Verification Matters
If you've ever used other free book sites, you know the frustration: you click on a "free" book only to find it's back to $4.99.
This happens because most sites:
- Rely on user submissions without checking
- Scrape data once and never update it
- Don't have systems to detect when deals expire
We built Book Deal Finder specifically to solve this problem. Every book you see has been verified as free on Amazon.
Our Verification Process
Here's how we ensure accuracy:
Step 1: Discovery
We discover free books from multiple sources: author submissions, publisher feeds, and our own monitoring systems.
Step 2: Initial Verification
Before any book appears on our site, we check its price directly on Amazon. If it's not actually free, it doesn't get listed.
Step 3: Continuous Monitoring
We re-check prices throughout the day. Books that are no longer free are automatically removed from our listings.
Step 4: User Reports
Users can report incorrect prices. We investigate all reports and update listings within hours.

What We Check
Our verification goes beyond just price:
- Kindle price — Must be $0.00 (not just "free with KU")
- Availability — Book must be available for purchase
- Region — We verify for Amazon US (amazon.com)
- KU status — We note if a book is also in Kindle Unlimited
- Goodreads data — We fetch ratings to help you find quality books
How Often We Verify
Not all books need the same verification frequency:
| Book Type | Verification Frequency |
|---|---|
| New listings (first 48h) | Every 2-4 hours |
| Active promotions | Every 6-12 hours |
| Permafree books | Every 24 hours |
| User-reported issues | Within 1 hour |
How Book Deal Finder Verifies Prices
Unlike other sites, we automatically verify every book's price directly on Amazon before showing it to you. This means you'll never click on an expired deal or a book that's no longer free.
- Real-time price verification from Amazon
- Expired deals automatically removed
- Goodreads ratings for quality filtering
The Verified Badge
When you see the green "Verified" badge on a book, it means:
- The price has been confirmed as $0.00 on Amazon
- The book is available for purchase right now
- It was verified within the last 24 hours
We also show "Last verified" timestamps so you know exactly when we last checked.
