CSGO item prices were taken directly from csgo.analyst. Not sure how much viable it is, but considering that these are the only traceable sales, and neither of the current sellers have anything else to provide, choosing the csgo trade as low end on being close to the tf2 trade. Let me know if this needs any fixing, I will get to it as soon as I'm free.
