The v6 items were just released and they are in very high demand. Alchemists want to make the most profit out of their compounds so they can afford to make more items and make more money. The high demand for these items is what drives the prices up. Like when v5 was released. I saw tons of people selling Christmas trees for an insane amount of gold and now you can't find anyone selling christmas tree and when we get around chrismas we might only see a few and they will be very cheap I think. New items are always going to be sold for an insane amount of gold because they are new. If you can I would wait a few weeks to let the craziness of the new version die down then I'm sure you will start to find some normal prices on the new items. I have a few items that I want to buy not because I need them but just to look cute while I train but I plan on waiting atleast a month before I buy them.
