My vendors in Trinsic(around 1841, 2688 in uoam, few blocks to the north from trinsic bank ) are now more or less fully stocked of the good stuff: wands, mana stones, g-heal kegs, town runebooks, bandages, kindling and scrolls.
You can also find few good looking invulnerability armors and pretty surprising weapons on sale too.
Penda, the vendor in south end buys star sapphires in the price of 240gp each. You can get a good pile of cash on this one.
