-Guy I got it from had a b/o at 15, I think it'd be okay to cap at 15 for this (buyout).

*Collectors Liberty Launcher Chem Set:

-Collectors Liberty priced @ 2.6 keys, chem set needs 10 ref more of launchers to completion, 2.6 keys - 10 ref = 2.06 keys, rounding to 2 keys.

27 + 27 + 15 + 2 = 71 :)
