Sell your unused stuff online with a browser agent doing the admin

A seller shared how they use ChatGPT's agent mode to sell things they no longer need. They upload a photo, add a few facts, and give the agent a clear brief. The agent looks up what similar items sold for, writes the listing, posts it to marketplaces from its own browser, and drafts replies to buyers. It stops so the seller can log in, approve each post and message, and check the facts. They report that during a ten-day sale, the agent cut their selling chores from two or three hours down to 10 to 20 minutes of checking. The agent can't confirm facts you didn't give it, get past some site checks, or ship items. Some people had trouble with logins and photo uploads. You need a paid plan.
