Foxtrot, permits cannot be transferred or sold. Only thing you could do is join someone else who just happened to have 3 extra slots due to people in their party cancelling, so you could join them. And that is probably never going to happen.
The best thing you can do is watch on May 1 for any permits that people won in the lottery but did not pay for. You have to be fast if you see any pop up.
Otherwise, we are hoping that Inyo N.F. gets the no-show process working so that those come available the day before a hike date.
