I just bought something (some new decks by Sulamith Wulfing) from Amazon and as always the recommendations for me were quite good. They tend to be good recommendations for me and I have gotten some of them more than once. This time they were all things I would be potentially interested in. Maybe mine are so accurate because I shop there SO often. I buy all my decks there and all my books. I happen to read a lot and have someone of an addiction to new decks. It could be that it gets more accurate the more frequently you use (?)

PS, 10 minutes after I wrote this, I got another recommendation from them for an audio book: Taoist Breathing for Tai Chi and Meditation: Twenty-Four Exercises to Reduce Stress, Build Mental Stamina, and Improve Your Health [Audiobook]
It went right on my wish list. I do want it but can't afford it just yet.
