What comes with my ipod touch gen5 if it is ordered online?

I would like to purchase an ipod touch gen 5 from the online store, but I do not know what comes with it. When I start to customize, it asks me what kind of accessories I would like, but they cost extra. So I would like to know what is included with the 199$ 16 GB version. And also I have been told that the 16 GB version does not come with a backside camera. I have a lot of questions and just would like some more information please.
