[MMMMMM]

1. If you don't believe in such things, pretend you do, for the sake of argument--or imagine you lived in Sir Isaac Newton's time, when such beliefs were commonplace.

2. You may sell out for monetary and/or non-monetary things.

Anything within the realms of wealth, love, success, etc. are easily within your allowed requests; also allowed may be some more exotic requests. They have to be things Lucifer is capable of granting, however. For instance you can't make it a condition of the deal that you will go to Heaven.

3. There will be no high-falutin' lawyers showing up at the last moment to get you off. If you sell your soul, the Devil will own it after you die. That doesn't necessarily mean you will be tormented in Hell the whole time, but you will at minimum be inescapably in the Devil's service and it will be at least a bit unpleasant at times. However you might become a loyal and favored servant of Lucifer in which case your lot might be better than that of others.

Also, you might burn in Hell if the Devil can't find a better use for you: that's his decision, since he will own your soul. If he spares you the torments of Hell, you will just be working in his service...until such time as Armageddon and the last battle and judgment, at which time, if Satan loses to God and his angels as expected, you AND Satan would be consigned forever to Hell. But that time would be a long, long ways off from now.

Things such as 100 million dollars, a harem of hot women, the single greatest love of your life returning your love, or fantastic health and a healthy ripe old age are all within your grasp for the mere asking. So too might be something like an accelerated cure for cancer.

So, what is the minimum would you sell your soul for, if anything?

So people won't ask for far more than their approximate minimums, presume that this is a public auction held in Town Square by a dark-cloaked man with red-glowing eyes, and that the lowest bidders actually get their wish. You have just seen the first bidder get his wish on the spot, too (a huge cask of ale, he being the town drunk), so you know that this is for real.
