Accidentally discovered a bug tonight in the PC version of Skyrim. It allows you to basically empty out any vendor taking all their items and gold. I'm posting it here in hopes of getting it fixed quickly because being able to do this completely ruins the game.

1 - Open trade
2 - Highlight an item for sale
3 - Move mouse over YOUR name (keeping item selected)
4 - Hit E and watch the vendor pay YOU for the item they just sold themselves

that explains why i often put some goldcoins in lootable corpses instead of picking the items up when i pressed E and not R for pickup while my mouse was somewhere i did not watch

Wow, that's messed up

What does E do? I wonder if this could be replicated on a console.
