They simply offer you a free eBook version with the purchase of every paperback book. This is true whether you buy the book directly from them or from a bookstore: >"Free eBook With Every pBook! If you are an owner of a Manning pBook you can get a free eBook at any time easily from your account. If you prefer NOT to have a Manning account no problem, we won't be offended: we will send you a one-time download link after purchasing the pBook at manning.com. If you did not buy the pBook from manning.com, you can still get the free eBook in all available formats by setting up a Manning account, and registering your copy."[1] It's also worth noting that you are supporting a a small independent publisher that's DRM free, as well as supporting independent authors. They also regularly have sales, often with 50% discounts, often on holidays. I wouldn't be surprised if there was a sale on Monday. [1] https://www.manning.com/ebooks https://www.manning.com/ebooks
