Is There a Balance Between the Spare Parts and the Currency?

Every time you kill an enemy, you are picking up what are called spare parts. Everything you kill drops spare parts between like two to 30 or forty on the challenge off the enemy. Those spare parts are also the currency in the game. Andi appreciated it though, is that their, the venders are sporadic. They're rarely in the same area. The most nervous i got was when i was horin around, like, cash in my pockets, money bags, and i'm like, noik. I'm got to lose all my money."
