List an item and handle buyer negotiation

A Meta Muse agent posted a Quest 3 on Facebook Marketplace and then managed buyer chats using a set floor price and a negotiation plan.

What they did
Meta Muse had direct access to the user’s Facebook account and Messenger, so it could create the Marketplace listing itself. After that, the user gave it a minimum acceptable price, a pushback approach for bargaining, and permission to reply to buyers without checking first.
How it went
The agent took over the listing and the back-and-forth with interested buyers. No final sale or price outcome was reported.
Tips
Set a clear lowest acceptable price and decide in advance where you will not budge. If the agent is allowed to message buyers, tell it to pause before any agreement that changes your minimum or pickup terms.

Try it yourself with Meta Muse

List my [item] for sale on Facebook Marketplace using the photos and details I provide. Write a simple, accurate description, then handle incoming buyer messages for me. Use [minimum price] as my lowest acceptable offer and [terms I will not change] as fixed conditions. If a buyer wants to buy, trade, pay, or arrange pickup in a way that changes those limits, stop and ask me to approve it before sending the message.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
