Why the same skin has 5 prices
Each marketplace sets its own fees and delivery model: Steam settles in wallet funds you cannot withdraw, on-site-inventory venues hold purchases in your account balance, peer-to-peer venues deliver through a Steam trade offer. Comparing every venue on every purchase — and buying where it is cheapest — is what compounds over time; cs2stack's own ledger has averaged ~38% below same-day Steam prices. The marketplace does that comparison for the whole catalog, and autobuy executes it for you.
