Contest Crazy

New to the diaper world, I am shocked at the number of opportunities for free diapers--Husband and I are currently crazed by the Great Cloth Diaper Hunt, and now I find that there is another month long diaper hunt in January, the Green Quiz Quest.  So this leaves me to wonder: what is the overlap between cloth diapering and giveaways?  I have to imagine that it is to large degree a thifty element--many of us are choosing to cloth diaper in order to save hard-earned money, and the thought of getting one precious cloth diaper for free is like fluffy diaper crack.
