You're not gonna get a deal for 135k unless you luckily meet an extreme noob who somehow has a Katana and sells it for 50k (which happened to me once and I'll never forget it)
10K! The luckiest I got was not from a sell it was some noob was carrying around a katana no armor or guns. Then I killed him and he had a katana. Best lucky kill ever.
Since I'm in the good holiday spirit, I'll sell you some katanas for 200k each (This is cheaper than normal)
