Sandbox options explained
Hello, I wanted to ask regarding sandbox options:
for example Rifle/Shotgun price default 100.

Does this mean that I can buy/sell Rifle or Shotgun for 100$
Or I can scan with scanner in my backpack Rifle/Shotgun and receive 100$ ?

So by adjusting sandbox options I could receive in this example for scanning Rifle/Shotty max 400$.

Or by adjusting prices it simply costs more for me to buy with module?
