Read the listing
Prefer a clear condition and a credible seller signal while learning the economy.
- 03
Inspect total cost
Add purchase price, missing components and repair time before committing to a flip.
- 04
Choose repair or donor
If a complete repair is uneconomic, dismantle the item for parts you will actually use.
- 05
Finish before listing
Clean, repair and reassemble the sellable device; avoid assuming a dirty or incomplete item will produce the intended margin.

Avoid the common trap
A rare or broken item is not automatically profitable. If required parts cost more than the likely finished value, keep the useful components and move on. Maintain a bill reserve before buying speculative inventory.
