The price for a download (rental or purchase) is significantly less than a hard copy, but I’m curious to know if you are able to reach so many more purchasers that it’s worth it. I’m also interested if you found that offering a downloadable version diminished your sales of hard copies. Is it a huge benefit to not have to worry with shipping/handling? What site(s) do you use for your downloads? If not your own site, what is the revenue split?
