I like to highlight a post in Curtis's ongoing journey on monetizing his Slopes app every so often to recognize the great work he's doing in education devs on how to make money on the App Store. You should really subscribe and read every post. He tries tons of stuff and spends a lot of time detailing it for our benefit. In this post, he talks about some ambitious changes he's made to his In App Purchase offerings. Find out what he's seeing.
