on Digital Pubbing:

When it comes to publishing, self-publishing can be a great option for authors. However, when self-publishing, you have to think of yourself as running a business. That means taking into consideration things like the cost of publishing (editing, design, marketing, etc.) and what the price of your book will be. And when pricing your book, remember to factor in how much other books in your genre are charging, how much readers would be willing to pay, and how much to charge for your ebook versus your print book (print books are more expensive to produce so you’ll have to charge more for them).

Speaking of print books, having your book available in both digital and physical forms is a great way to expand your reach. (And sometimes, you might want a print-only version of your book, like if you’re creating a coffee table book.)

If you do want to offer print versions of your books, there are lots of print-on-demand options, (POD) so you don’t have to store a bunch of copies in your garage.
