Mannco.Store Market

Creates Steam trade offers for Mannco.Store P2P sales. Steam cookies stay in your browser.

Mannco.Store Market is the official browser extension for first-party P2P sales on Mannco.Store. When someone buys an item you listed, the extension creates the Steam trade offer from your account in the background. You stay logged into Steam in the same browser. Steam session cookies never leave your machine. What it does • Sends the Steam trade offer for each P2P sale assigned to you • Shows pending offers in the toolbar popup (item name, image, you-receive price, Steam offer id) • Reminds you when Steam Guard still needs a confirmation • Reports offer status (waiting, accepted, declined, canceled, expired) back to Mannco.Store • Keeps you marked online so your listings stay visible on the market What it does not do • It does not send Steam cookies or Steam login tokens to Mannco.Store • It does not create a second Steam offer for the same sale • It does not withdraw items from Mannco bots or touch the custodial market How to use 1. Install the extension 2. Log in on https://mannco.store in the same browser 3. Stay logged in on Steam 4. Open the toolbar icon — Mannco and Steam should both show green 5. Keep the browser running while you have live listings Support: https://mannco.store/support
