Confirm exactly what is being sold
Make sure the model, generation, size, capacity or relevant variant is clear. Whenever possible, photos should show the actual item and the visible details should agree with the title and description.
For bundles, ask for a clear inventory. Standard accessories, optional extras and separate major products have different implications for both value and risk, so a vague “bundle” description should not be treated as a known quantity.
Ask for documentation that fits the product
Useful documentation depends on the item. It may include a receipt, serial number, battery-health screen, usage hours, service history, proof that an account lock has been removed, or close-up photos of specific damage. Ask for evidence that actually helps verify identity or condition rather than collecting personal data without a reason.
Be cautious with pressure and unusual payment requests
Strong time pressure, requests to move the transaction away from the marketplace, or unfamiliar payment methods deserve additional scrutiny. When possible, keep the transaction traceable and use the platform payment flow or buyer protection that applies to the purchase.
No single warning sign proves fraud. Consider the combination of price, communication, documentation, product identity and how the seller wants the transaction to be completed.
Agree on how the item will be checked
For collection in person, agree which functions you want to test. For shipping, document the listing and confirm the item, condition and included components before payment. Keep the relevant listing text and communication in case you later need to understand what was represented at the time of purchase.
