Amazon is running a special on select book bundles where you can save up to 60%. They start at $4 for Kindle Edition series.

If you look at the number of reviews on the WHOLE bundles, there are very few. But if you click through to the series you can see the reviews for each individual book and they are much higher. For example, the "Kricket Series" only has 12 reviews. But if you look at the individual books, the first in the series has 4.5 stars on over 1000 reviews. I think I may try that one!
