Good Day,
I am currently paying 30PP each or 600. For Oak Bark. A forageable item in Kith, and ground spawn in BB. There is 20 nodes in BB they look like little green pucks. They are on a 20 minute timer each. If you are good with locations and wheres waldo this will be easy for you!
Here is a refrence with all the locations.

PM me here or message Djones in game. No collection of Oak Bark is too small or large! 15minute response time on the forums most hours of the day.
