I know many of us are keeping an eye on certain items to see if the price goes down. Or sometimes we just come across a really good deal by chance.
Here's a place to share good finds in the marketplace and/or new items with our fellow guild members.
I found a thread in the Gaia main forums with the same purpose. Since it's a thread that many more people will see, it might cause the prices to fluctuate quite a bit more. But it still might be interesting to check out.
