Clean out your stuff, and “toss it out” to another player/swapper.
Cost: The postage varies with how much stuff you send out and how you send it.
There are various ways that this is done.
1. Players sign up and post what they have, other players contact to get what they want off the list.
2. Players sign up and are assigned a person to sent their tossed stuff too.
Time element — this can be within a short specified time span OR it can be an extended time of a few months.
