Chart: Exotic Mini Buy/Sell Profit Margins

 
This table shows the profit margin for each of the Exotic Miniatures in Guild Wars 2, calculated as a profit on return percentage.

The big caveat in the demand bars is how many useless bids are sitting at the bottom of these listings. I need to find a way to strip that data. Sounds like work to me.

Calculations:
Profit Margin (%): (ask*.85-bid)/(ask*.85)*100
Demand: (listings/offers)/10
