A couple of short Kindle books for $0.01 today (normally $2.99) on the topics of how to improve your Kindle book layout with HTML and some good advice on making quality pictures for a Kindle book.
I've seen only the "Click to look inside" but the advice I saw in both looked very useful and well-written for Kindle books that you can get tonight and maybe tomorrow, for a penny each, or $0.01.
I don't know how long this sale has been on or how long it will last, but they're generally 1 to 5 days tops.
Both of these small Kindle books are only 68 to 69 pages long.

Hope they're also at this price tomorrow. I just happened on these tonight.
They're both published in the last two months, and the feedback looks good.
