Throw It Forward is for US (some exceptions) yoyoers that want to participate in a traveling mystery swap box. The cost is that of shipping plus a yoyo to trade and some gifts for the next recipient.
Basically you get the box, trade a yoyo and goodies, and ship to the next person.

There is a new box about to start with yoyos in the $25-50 range.
