How to Make Money from Steam Games by Selling Commodity Items

A lot of Steam Market income comes from commodity items — cases, crates, keys, capsules, and other stackables — not from flipping unique skins. Multisell is how you list a bunch of those stacks without losing an afternoon.

What people actually sell this way

Cases and crates, keys for those containers (when they’re commodities), and capsules or similar packs. If it stacks and Steam treats it as a commodity, multisell can handle it. Fancy one-off skins are a different workflow.

How to get set up

1. On Steam, turn your profile and inventory to Public so your commodities can be loaded.
2. Open Steam Bulk Sell and pick the game you sell for (CS2, TF2, PUBG, and so on).
3. Paste your public profile URL. Items you can multisell show up automatically. You can search for items manually if you want — most people just paste the URL.
4. Select what you want to sell, open the multisell link, and finish prices on Steam while logged in.

No API key and no extension. Public inventory is for the load step; you can lock things down again afterward.
