I'm selling mark scrolls for 31 gold each. I currently have 200. You can buy them all or just what you need. Since I don't use in-game chat, you'll have to send me a PM through the forum to arrange a date, time and meeting place for the transaction. I'm in the Central time zone and usually on in the evenings (after 5pm).
Update: These mark scrolls are now on my vendor in Vesper, which you can find out more about in this post: viewtopic.php?f=76&t=67180
