Sales at:

36

38

41

53

53 is a large outlier, as supported by the sellers. Excluding 53.

Ignoring the fact that the sale at 38 quicksold, given how many sales there are at, or lower than that price.

Scrap.tf was paying 36, but they’ve lowered their prices, and would be paying a bit less than that now. Keeping 36.

Going with 36-41.
