Here is a 30 card expansion set for your Cards against humanity set.
Had to buy it for myself as soon as it came out and got the last two expansions, totally worth all the monies. If you already have it enjoy this cheap expansion, if not buy the original game and all the expansions :3
Not for kids or those easily offended I can't even really give examples of what the cards say but it deals with a lot of sexual topics nazis and other things some sticks in the muds would get offended about.
Thanks @rabidmonkeyoncrack for showing me this deal.
