Excluding 18 and below.

20 quicksold both times. Excluding 20.

Sale at 63 MIGHT be an outlier. Excluding 63.

2 month old seller at 26 shows that 26 doesn’t sell well, and therefore, should not be included in the range. The sale at 26 is also not the best sale to use, as it consisted of quite a lot of small-ish items. Excluding 26 and 29.

Going with 22-25.
