Ahh, but there is a way to get a vendors entire inventory. Let me tell you about a little thing my brother and me have come to call the "curse bag" in our divinity games.
When you kill a vendor you only get a little bit of loot, usually some of the things they sell will drop. They do however also drop every item you ever sold them. This means that if you have enough items to trade them for their entire inventory you can then get what you traded back by killing them.
At the start of the game it requires a bit of work. You simply pick up absolutely everything. Sea shells, sticks, candles, cloth, crates, fish, socks, shovels. Everything!
Put that in a backpack and trade the backpack to the least important vendor in your area. Kill the vendor, and put that vendors items in the bag. Now you have a more valuable bag to sell to the next vendor.
The name comes from vendors who come to pocess this bag of enormous wealth tended to meet a terrible end short after.
