If you have already looked at the numerous resources I have purchased, you are probably looking at your computer like this by now. LOL. STAY CALM. Although I have obtained an abundance of resources to teach my son, I am also very cost-conscious, (ok fine, I am cheap). But my frugality is to your benefit because I have learned through conducting price comparisons and overall experience the best places and ways to get a good deal without skimping out on education.
