I'm looking into publishing my book in Kindle format on Amazon. I'm surprised at how possible it is to do this without financial outlay.
For instance, I didn't know that by law the copyright is mine without having to register with the copyright office. If I choose to register it (better defense in the event of a court case) I can do so online for just $35 vs. $65 to register by mail.
If I could make up my mind about a cover picture I could get a professional cover design on www.fiverr.com for just $5, vs. $100-200 for a professional IRL.
It costs nothing at all to list the book on Amazon. They take a commission on each sale, but there's no upfront fee. For electronic only I don't have to buy an ISBN at $125, Amazon supplies their own number for tracking purposes.
epublishing is really a frugal strategy.
