In Nevada instructors can charge what they want, I paid $105 plus I think $50 to get Utah done at the same time. I did see courses as low as $65 and last year the gunstore was giving them free, but from what I have heard, that is still too expensive for the gun store to charge.
There is much more involved though, in the end it cost me around $400 or maybe less, as I need a good IWB holster, plus fingerprinting, and the actual fee for the license. If I remember correctly.
