that practitoner is gonna need an update

all sellers in classifieds(at time of posting this) are at 35 or below as well

The 4 keys in sweets added with the Cannonball don't match, and the Practitioner is outdated (19 days unsold at ~27):

So that sale will be around ~30 keys. You also missed a lot of sales:

So in summary there are sales at ~30, 33, ~33, ~34, ~35, 36, ~40, ~40. The sales at 40 are countered by sellers/unsolds, so 30-36 should be the range here. Feel free to resuggest at that.
