One swap I enjoyed a lot was the host put as many items in a one price mailing box that would fit. She mailed it to the next person who took out what they wanted and added that much more to the box and mailed to the next on the list. The host then received the box last with all new items. The rule was to replace the items you took with other quality items. Everyone posted what they kept not what they replaced it with. It was a lot of fun.
