I have begun ordering our school books for the fall. I love this time of year!!! I walk down the school supply isles and gaze at all the pretty binders, the pencils, erasers, and notebooks. I look online for the best deals, many times having at times 4 tabs open to various sites of books to find the absolute best deal. I have 4 at the table this year which means that I have to watch how I spend the school budget. I made a book chart for myself in order to keep track of what subjects I needed for which kids, and how much the books were at retail as opposed to the actual cost. I love watching the retail column and the cost column differ. It makes me feel good. If you need something like this I have the document with formulas on our family website, located in the Resources tab, to save and use for yourself.
