For trading when 1 side doesn't have an idol:
If you don't have an idol, you need an alt (or friend) and you need a character with at least theft skills (any skill that leaves summonable scents will do).
1. you create summonable scents with the character you're gonna trade with
2. you give those scents to an alt or friend to summon you back when the trade is over
3. break your hearth fire
4. get oathed to your trading partner's idol
5. port to the idol
6. conduct the trade
7. log off (keep in mind that because of this phase you must limit the quantity of trading in 1 trip to only what you can fit in your inventory)
8. get your alt/friend to summon you
9. log in
10. ...
11. profit
