To copy my comment from the suggestion you use this as mini in (https://backpack.tf/suggestion/677ec5907a74cafe8002cf0f):

"Everything about this is wrong, I didn't pay 251 keys + the war paint for the stormy 13th, and whatever I did pay is not the complete trade, as I owe a portion of the possible resale price to the previous owner. So no, I did not pay "586 keys mixed" for a just priced stormy 13th unusual. My asking price on the war paint was 500 keys pure before I sold it anyways, nothing about this is right.

Basically, the trade I did with "Starlight Serenity" was a combination of item overpay + a contingent payment agreement, not a full sale by any means. It's better to leave this at its current bptf price and the war paint unpriced, as the complete trade has not yet been finalized regarding these items. You can confirm this with "Starlight Serenity" if you want to."
