Inside the cache there are two ziplock bags. One bag is to leave any extras of your personal card to let other people (especially newer cachers) have one without trading. The other bag is for trades only; so bring the extras and trade even (1 for 1) or up (drop 3 take 1). Once the 2014 cards arrive this would be a great spot to drop off a few.
