Ask HN: How do I turn off/disable all aws services without deleting the account?

Ok so I signed up for an AWS account to work on just to explore it. I must've turned on Kinesis and S3 to play around as well. I must've used it for one maybe two days and I have $10 charges. It is isn't a lot but I don't want to keep getting charged for something that I'm not actually using. I've googled around and couldn't find a clear answer. How do I turn off all these services?
