Roughly how much does it cost to have my teeth whitened?

I want to get my teeth whitened and was wondering how much it costs? I really do not know anything about it. Are there different methods?
--------------------
There are different methods. To do it yourself, with strips or whatever, only costs maybe 30-40 dollars, but wheter this is effective or not... professional whitening is going to be at least a couple hundred dollars, depending on how good the dentist is really and what kind of method they do. If you're curious you should ask yours or a specialist.
