Fallout 2 could probably count. A number of merchants in the game store their inventories either on their person or in the shelves next to them, so you could potentially just steal everything you want with no consequence (assuming you aren't caught).
Hell, there's a vendor in San Francisco that carries a bunch of high-end armor, weapons, ammunition, and a large amount of money. For whatever reason the money is always in his personal inventory, so you can just pickpocket it from him, buy stuff from his store, then pickpocket the money back.
