Not sure if I can explain this well....so feel free to ask followup questions. Exchanges are basically gift exchanges through the mail. Currently there is the ornament exchange. There is usually a mininum you can send (1 ornament), some send more. You sign up for the exchange, receive the name/address of the person you are to send your ornament to, then send out the ornament and wait for your's to arrive. There is also a mail by date. This year the ornament has to be mailed by 12/10. The sign up for this exchange is closed, as well as the sign up for the yankee candle exchange.
