This post is a budget update, which is how I track spending throughout the competition. Check out my budget to see what I've spent money on.
To be an Apple Developer, you have to register with their developer program. I have no problem paying the $99+tax since I love the developer program they have in place. I enjoy working in Xcode, notice fast download speeds, frequent beta updates, and so on. Overall, it is a pleasant environment to work in, so please take my money.
