Sales: 25, 25, 25, 25, 25, 25, 24, 41, 17, 18, 20, 20, 19, 23, 19, 20, 9, 27

Lower sales and sellers should counter the 25, 24, and 41(?) key mp.tf sales. 9 is below buy orders. 27 is obviously gonna be high and I feel comfortable ignoring the 23 key sale too since there are numerous cheaper sellers now.

Final price: 17 - 20
