I have set up 10 trading booths in attached to the side of my house. I have done this so that people who wish to find a safer way to trade have an option other then running until people stop following them.

These booths work by keeping the doors closed as long as someone is standing on the pressure plate inside the room so once both parties are in one of them steps on the plate. Make sure no one else is in the room with you and it will be that much harder for people steal your trades. You still need a bit of personal Vigilance as it is possible for people to do shady things this just makes it a touch harder.

You can get to these booths use the town portal to Angels Rise this down one floor and straight ahead.

Once through the portal follow the sign that says Trade booths. Pick a booth and trade that much more safely.
