CS2 skin deals, under the Buff163 ask, page 4

Pay the ask, list the skin on Skinport at its recent sold median, keep what is left after the 8 % fee. It is a patient seller's number, not a same-day flip: selling at the median means waiting for a typical buyer rather than undercutting to go today. When the last day of sales ran below the weekly median, the exit is marked down to the fresher figure and the row says so. A round trip that looks too good is flagged suspect; that is usually a thin sold median or two variants of a name that collided, not free money.

A cross lane row is a real spread between two venues you can trade on, net of fees. A reference lane row is a discount to the Buff163 price, which anchors fair value but cannot be settled from Europe, so you still have to sell it somewhere. Each price on this page opens to say what kind of number it is, where it was read and what is missing. Fees for every venue are on the marketplaces page; the sold medians behind the exit come from Skinport.
