Look at how long that elbow joint has been on the market,
"4th July 2015" (I can take a picture if you want)

Also Smallbowl's joint has been on the market for 9 days.
These would classify as items that don't sell very fast.
I also know for a fact Smallbowl paid about 5.5k for his, so If i paid anymore than that he will just keep undercutting me.

So, those are my prices for the items sorry m8.
