Today was a great day to try to control some markets for part of the day. Many items were completely out after the 24hr server downtime. If someone beat you to the post, just buy em out and repost for major profits. I found a stack of Large Brills for 3.5g each, and knowing they usually go for 10 each, I bought em all and flipped for 15g each, then they all sold out within minutes. Speaking of which, Tuesday after the servers come up is a good time to try this as well.
