Store

 * His store is open from 3 pm to 8 pm (unlike other stores, open approx. 8 am to 6 pm). He will sell to you at other times if you find him. He sometimes sells blood packs at the regular "junk item" price (base value 5), which can then be sold nearby to Vance for 15 caps (not subject to Barter). This is only possible if you have brokered a deal with Vance and Evan King of Arefu.
 * Karl also has one of the biggest merchant inventories in Capital Wasteland. His inventory is located in a freezer near his desk.
 * He stocks around twenty pieces of scrap metal at the start of the game.
 * Some of the notable items he may sell include 2 Stealth Boys, an advanced radiation suit, a Nuka-Cola truck and a fair amount of microfusion cells.
 * Karl's valuable store is easy to loot when he isn't there, except for one medical kit with a hard lock.
 * Unlike anyone else, Karl never runs out of stimpaks to sell.
