Um.... I should have been clearer.

If my case is all orange Sandtroopers (as I assume it will be), then my plan is to trade a Orange Pad Trooper from the case to one of those guys I am splitting the case with for the White Pad Sandtrooper. He has the white pad sandtrooper (he bought at comics shop), but he doesn't really care which one he has, so he's willing to swap white for an orange if I need to find one!
Under this scenario, it'll look like this:
1x Greedo - for me
1x Tusken - for me
1x Obi-Wan - for me
2x Cantina Band Member - sell 1 to pal #1, sell the other to pal #2
3x Han - sell 1 to pal #1, sell 1 to pal #2, 1 extra/leftover
4x Sandtrooper (Orange Pad) - Trade 1 to pal #1 (for white Sandtrooper), sell two to pal #2, 1 extra/left over
BUT, if my case does indeed have white pad sandtroopers, well then, I'll just get one from the case and pal #1 won't care about trading since he has a white Pad Trooper.
Under this scenario, it'll look like this:
1x Greedo - for me
1x Tusken - for me
1x Obi-Wan - for me
2x Cantina Band Member - sell 1 to pal #1, sell the other to pal #2
3x Han - sell 1 to pal #1, sell 1 to pal #2, 1 extra/leftover
4x Sandtrooper (White Pad) - 1 for me, sell two to pal #2, 1 extra/left over
Either way, I end up with a White Pad Trooper
Sorry for the confusion, I was just trying to cut to the chase without all the messy details that I have now caused you to read!
