This is confusing me, as ppl tell me it goes up on weekends. But i think that as more people are online and playing more on the weekend, then more stuff or supply will be available on the Auction house which will result in price cutting leading to and overall decrease in pricing.
best time to buy is on monday morning best time to sell is on wednesday everyone wants to sell their stuff before school starts so prices are lowest on monday but best time to sell stuff is on wednesday when the majority of the stock is gone
