Write the ad the way buyers search

Put brand, model and size in the title, and describe defects openly in the first three lines. Ads that name flaws get fewer but far more serious enquiries.

  • Four to six photos in daylight, including the defect
  • Measurements, age and original purchase receipt if available
  • A clear statement on collection or shipping

Private seller or trader?

Selling your own used belongings occasionally is private. Buying to resell, listing dozens of similar new items, or selling continuously makes you a trader — with imprint duty, statutory warranty and a right of withdrawal for buyers.

Handover and payment

Meet in a public place, test the item together and write a two-line receipt naming both parties, the item and the sold-as-seen clause. For shipping, use a tracked service and insure the declared value.

  • Never accept overpayment with a request to refund the difference
  • Avoid payment links sent by chat — they are the most common scam
  • Report suspicious contacts through the report function on the ad

Frequently asked questions

Can I exclude liability entirely?
As a private seller you can exclude warranty for defects, but not for defects you knowingly concealed.
Do I have to accept returns?
Private sales have no statutory right of withdrawal. Traders do.
