I believe in common courtesy. This means I'll try to pick up or deliver items fairly promptly or attempt contact within 48 hrs. It also means I understand if you're in game GAMING (not just standing around GTOB).

Since I'm usually on evenings and on and off during work hrs UTC-7, pls let me know a time range and we'll work it out.
I also like leaving comments with my ratings. It helps people know what those ratings involved and why I liked trading with you.
