Royalty free self publishing is something that you need to really pay attention to. Some book printers will not say they are royalty free, and this means they can keep the rights to your book. They can sell it to retailers, as well as market your books to people other than your target audience, which will increase costs.
We stick to what we do best, book printing. We don't sell or market your books. We print them, and we do that well.
What you write is what you own. DiggyPOD will not take credit for your book, nor will we charge hidden fees to print your book.
Nobody owns your book but you when printed through DiggyPOD. Other book printers will sometimes claim rights to your book, not us.
It's called self publish for a reason. What is the point of self publishing when you are paying another printer for royalites? You don't have to worry about that with DiggyPOD.
Just because DiggyPOD doesn't market your book doesn't mean its the wrong thing to do. There are companies out there that will sell your book, and might even put it in front of the correct audience. Just know that with DiggyPOD, you get a great looking printed book, with none of the hidden fees.
