Amazon �48 rip off.....?

They have the terms and conditions posted there for a reason. That is so that you can read them and be informed about what you are signing up for. I think if you read through them properly you will see that there is something about automatic deductions after the 30 day trial if you don't cancel it. I would contact Amazon and complain about this if I were you. Nothing will change unless people say something but I suspect you didn't read the conditions and so you know you don't have a leg to stand on. Read things next time.
