It's not "playing": reading is fundamental. Their billing rules are clear. It could be argued that their vocabulary for describing the billing rules takes a bit of figuring out. I have a client that didn't understand either the rules or my instructions and did something silly and ran up a $5000 bill, when he was thinking it would be $100~$200. We called Amazon and they cancelled the bill.
Amazon is very easy to work with, if you simply tell them that you are an idiot and fucked up. You're not the only one.
