How do I contact a seller about a listing?

Open the listing and tap the message button. That starts a chat with the seller about that item. You need to be signed in to send a message. How it works: • Each chat is one buyer and one seller, about one listing. Only the two of you take part in it. • You cannot message your own listing. • Ask what you actually need to know: is it still available, can you see it today, is the price fixed. • You can also send an offer instead of a plain message as your first contact. About the phone number: the seller's phone or Zalo is not shown on the listing page. It appears inside your conversation once the seller has replied to you at least once. This keeps sellers from being spammed and keeps your own number private too. If a seller pushes you to move to another app before replying here, be careful. A deposit sent outside the chat leaves no record anyone can check later.
