Someone had mentioned having a small swap meet along with this meet. I figure this would save on shipping for many people.
Post what you have for sale or trade and are willing to bring with.
Try to keep one post for each person, if you have more just edit your post.
Mark your items accordingly with Interested/Sold to Buyers SN.
PM the seller of the item you want.
Include in PM that you are going to be at the meet.
No public requests, PM the seller if you have one.
