Safety tips

• Check the item very well and ask questions before you buy it.
• Unless you're paying via Selloff Escrow payment on our site, you are advised to not make advance payment before delivery.
• If you're picking up an item, ensure you meet in a public place: Never meet with a seller in a secret and lonely place. If you ever have to meet up with a seller, ensure you do so in a public place you are familiar with where you can get help if the worst arises.
• Secure your account by using a strong password.
• Report suspicious activities immediately.
