Charges you after limit without warning you

I buy apps all the time. Had I known I was at the limit (maybe used it 5 times over a month) I would have bought whatever version I needed. This app gives you know warning that it will charge you though. I work this morning to find an iTunes bill in my email. Thats pretty shady. Just let people know.
