Go inside the resource and open: "shop-client.lua" and change this:
local weapons = {{31,3500},{4,15000},{5,500},{6,1500},{7,3500},{8,10000},{9,12000},{22,2500},{23,2700},{24,4000},{25,4200},{26,9000},{27,8000},{28,6500},{29,7000},{30,3500},{32,7800},{33,11000},{34,16000},{16,20000}}
to this:
local weapons = {{35,16000},{36,20000}}
And then change:
