This is a pretty awesome deal when you consider it for a whole family. I go through a couple books a week reading with my daughter (generally in Kindle format on an iPad). We get what we can from the library, but she really likes series, and if we finish book 4 while book 5 is still a two week wait to check out I'll typically just buy it. Throw in my personal reading and my wife's and we're buying an average of 3-4 books each month.
