If you have a Kindle, iPad, Kobo, or Google Play, you can use this free and cheap service. After you sign up and choose categories of interest and your reader, you will get daily emails with free and cheap downloads and you can search their site as well. I downloaded "Murder in Provence" for free the other day and a Mother Teresa bio for free as well. They also go to my Kindle app on my iPhone….ain't technology great!
Here's a review….very positive. There really is no downside as I can see.
