Who ships first?
This should be worked out on an individual basis. If you trust the person and have researched them, then there shouldn’t be a problem with whomever ships first. One of the more important things in trades: KEEP IN CONTACT. I have been late before but would always let the person I’m trading with know that I am behind, and to not worry. The worst thing is to be in a trade and then one guy drops off the face of the earth for a month.
