Scrap the most basic component, which should be very cheap. However, it is used in almost everything, and you can never have enough of it. As a result, it is highly sought after and can be sold at exorbitant prices, ranging from 5000 to 8000g per piece!

This means that everything made from scrap and those further down the line are significantly more expensive than the in-game price.

Some of those are:

• Screws
  
• Nuts
  
• Hammer
  
• Broken Knife
  
• Toolbox

However, as I previously stated, all items can be broken down.
Extinguishers, for example, can be purchased for around 70,000-100,000g but dismantled into 30 scraps worth around 200,000!

That is, if you dismantle instead of buying scrap, you will save 50% every time. Furthermore, if you use your sellable scrap instead of selling it, you lose 3,500g for each piece.

Plastic is cheap, but many of the things you can make with it are worth a lot of money and can easily earn you 10k-30k per piece. My secret item costs less than 10,000g, but can be sold for 100,000g at specific times of day!

• Glue Gun (200k-250k)
  
• Soldering Iron (700k-850k)
  
• CPU (1.5m-2m)

If you looted any of them, don't sell it to Heidi!
