So I was going through on my iPhone getting some music from the Wifi store, and I watched my store credit go down just $.99 with each song. I then tried getting some music on my mac and it did the same thing. Yesterday, I got charged $1.05 for each song, but not today. This probably has something to do with the fact that IN sales tax changed from 6 to 7% today. Has anyone else in Indiana experienced this?
