I'm planning to do a bit of research before my next post so it might be a few days in the making. Until then I just wanted to point out the total abundance of interesting resources I have been finding on Amazon. As you can see in the disclaimer above, I have decided to join their "associates" program and create my own focused store. In the past, all my Amazon searches were very focused. This time I started running wide searches and I collected so many interesting options into my store. Right now I have more than 150 products, mostly books, and more are to come. I will also add categories to make it a bit easier to find stuff. I hope you find this a useful resource.
