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 ;))
this is AWESOME with a capital AWESOME. This makes it SO much easier to control my spending, see what item I can afford at the cost it is worth. I appreciate this. very. much.
