      This is my little storefront for my books, tutorials, and other things...
      I ship orders every Monday and Friday :]

      NOTE: Some shipments may be delayed slightly on the week of June 8, I'm visiting an ill family member (but brought some stock w/ me). I will email to let you know if your order is delayed more than a few days. Thank you!

      Thank you very much for looking!
