Whether you replace an item with a new item or a used item depends on three factors:
- whether you want a new or used item
- whether the item is still manufactured or sold
- whether you have enough money to buy a new version.
Additionally, many people choose to buy "gently used" items to help conserve the natural resources. Every manufactured item uses some type of fuel for manufacturing, whether the fuel is electricity, gas, oil, coal, etc. So by buying used, you can help save the earth's resources.
