You may have noticed some new information on the item popups, as well as the trades :)! We are now collecting data on the average prices of items, that will be displayed in various areas of the site :D
Over the next few days, this will be improved to show both the daily average (as in, just today) and the monthly average (so if someone trys to increase the value of an item today, you'll be able to tell ;))

Trying to control the Inflation too much.. Its suppose to go up and down
.. Sticking a lower price on items that are worth more probably aren't going to help. Maybe if you release more it might.
