This topic is almost, almost as over discussed as Glock prices.
Until a sailor actually hands you the item and you say "Okay", there is no real sales agreement on ODT. That's why we need a primer for newbs. You can agree to buy something from a sailor via PM and that means nothing. The sailor is free to entertain other offers after they agree to sail to you. That's what makes ODT unique. You DON'T have to have to honor here.
It's the ultimate neckbeard haven.
