Pack up old board games (even if missing pieces or only $54 left in Monopoly) and ship them for free to Recyclebank for points towards valuable coupons. Just take the onsite pledge to recycle your old games on that site and you can print out a free shipping label to send the games in.  Recyclebank then sorts and recovers materials for distribution.  The rewards are high value coupons for a variety of foods and consumer goods.
