Smashwords often has free titles. Authors give Smashwords coupons. Gifts of ebooks are given through Smashwords. But you own a Kindle and hate to manually upload ebooks.
I have a solution. Set your Kindle account to receive emailed attachments from your computer. Treat the new ebook like a personal document. First, when you download the ebook from Smashwords, save it to your desktop. (This is for ease of finding the ebook. If your computer is anything like mine, it likes to hide documents and let me scream at it all day until I find the thing. They're evil like that.)
Then, you must register your email account. Do it here.
Once you have a kindle address, using your name and either "free.kindle" or "kindle.com"
simply open your email program, and attach your free ebook to your email to the above address. You must make sure that Kindle knows your personal email address. It's like not answering the phone when you see it's someone you don't know. Kindle likes to know who is sending it stuff.
Then all you have to do is turn on your Kindle, turn on your wireless, and it will download automatically.
I often download whole group digests, or large files that I want to read. It's easy, and I read them wherever I am relaxing. Try it. You'll love this feature.
Now, buy my book and try it. (Just kidding)
