You have to restart GTA to get the proper discount number.
I hope someone over there made a whopping mistake though, because on war stock it says you need to fly 5000, yes, that's 5 thousand!! Sourcing runs to get the discount. Either someone put in two too many zero's or R* have lost their minds.
Personally, not restarting my game as I have no interest in it anyways just from Foxy testing the damages and all.
I'll appreciate it from afar.. It looks cool and all but not worth the price or anything..even if I do have dupes sitting in garages.. lol
