One of each of my award-winning I DO Know Jack! cards. Ten cards in all. Series 1. Great stocking stuffer! These retail on my website for $3.75 each which is already a discount off of the regular $5.00 price at retail stores. These are rock bottom at $2.75 each when you buy the whole (10) Series 1 card set. (Does not include Gutshot Jack, Car Jack, Jack and Diet Coke and Jack of Hearts.)
