Indie Author Essentials (your guide to going wide) : Sell D2C – get over 90% royalties! Get started D2C the easy way with Shopify and Etsy! [EPUB ebook] 

• Etsy – how savvy indie authors can reach new readers and bring in new revenue streams by selling our work in this exciting global marketplace.
• Shopify – no, nothing to do with Spotify, the music subscription service. Shopify is a great way to sell our books and other products direct to consumers, from our websites and blogs, from a specially created store, or even direct with buy buttons on Facebook, twitter and Pinterest.
