A trade-up contract is an in-game CS2 mechanic by Valve. This site does not trade, does not accept items and is not affiliated with Valve Corporation. Prices come from external markets, refresh hourly and may differ from the live ones; buying ten lots at the shown price is not always possible. On top of the selling fee there are deposit and withdrawal fees, and an item bought on a third-party market arrives by trade and cannot be resold on Steam for seven days. Expected value is an average over many repetitions, not a promise about one attempt: for most contracts the chance of getting back less than you spent is above 50%.
