A few emails have shown me people are not sure how to Sideload eBooks! You need to be able to do so if you shop Smashwords or my eStore. I've summarized the process into five easy steps (and found some insightful YouTube videos): Sideload
Once you've done this process from start to finish once, and are used to it, you can literally do this in minutes. I have added a version of these instructions to my store, and a link in the download email to the instructions (for future reference).
