Books! Books! Books!

Ok, I really need to stay out of bookstores and amazon.com.  There are so many books out there that I want to purchase to help me with my students but I can't keep buying them all!!!  And now, with my ipad, it is so easy to just click the kindle edition and poof, I have the book in seconds. 
This morning, I already have found several that I want to purchase and I already purchased 3 books this weekend. 
Add to that, all the fiction books that I want for my classroom and you see that I really need to be winning the lottery!!! 
I purchased In the Middle by Nancie Atwell, a Fontas and Pinnell book called Guiding Readers and Writers and Janet Allen's Tools for Teaching Content Literacy. 
All of this resulted from attending a workshop on Friday!!!  Is there anyone else out there that has this problem???
