If you want to "make a deal with the devil", then go to your local church and be a christian and sell your soul for death.
On the other hand, if you want to empower and advance yourself into Godhood, where you never die, and have health and youth and the ability to shape your world as you want it, to improve Earth and Her Inhabitants and kick the shit out of the bitch losers, or loser bitches, who have been raping this Planet and these Peoples, and while doing that you'd be supporting Satan and His Cause and Our Side, then you can dedicate your Soul to Satan, who is not "the devil". If you are selfish and want to earn some quick money, for example, and then flip Satan and Spiritual Satanism off and ignore the point of what Spiritual Satanism is actually about, then you won't get far and your dedication would more than likely be ignored.
You should visit these sites and go through them carefully and understand the things on them.
