The above sums it up well.
If it were so easy/simple selling parts, then pretty well everyone would do it as a source of easy income. The back and forth on negotiating the price of the item, finding the packing materials to ensure it’s not damaged in transit, then getting a shipping quote all while realizing it could be a flake buyer who ‘claims’ they never received the package means it’s not ‘easy money’ selling parts off the side of your workbench.
