I think that at all servers we have beem seem that bazaar is REALLY inflationed :( By myself I try to hold on any buy till get a fair price, yesterday for example, I bought an ornate silk robe for 58k that, I think, is a fair price. In my humble oppinion not all people in bazaar has the ability (or desire) to sell and buy things to get profits, most people are just trying to sell things to buy better things for their characters and when they see the prices going up they just bring up their prices too (I will not discuss the reason behind it). If we just stop to buy till find a fair price on the item that we are willing this will help to increase the offer and the prices will go down. I usually wait for one week or two till find an item on the right price, with some pacience it appears. The problem here is the part of "what is the fair price?" Sites like allakhazan may have a great role at this point. Allakhazan has the prices for many items on the servers and this can help :) Here we can sell and buy items outside the game as well :) Just to instance another example, I saw an ornate silk glove for 15k on the market channel :) Just be pacient and buy with wisdom, don't let the prices go to the sky :) An ornate silk robe will never worth 200k or even 100k :)
Another point posted here is that some items that you can buy on LDON vedors are really great and with time they can became equal or even better than the ornate one :)
Let the people that overprice items with their items in their bags :) If they are really players, they will put the price down after one week without sells and if they aren't really players they will not reach their objectives and leave us to play :)
This theory works for me :)
PS. Sorry about the bad englsh :)
