Other World Computing (http://eshop.macsales.com/) is offering free Exhibit Hall passes to MacWorld SF. Download the .pdf from here, print it out, and bring it to the registration desk at the Moscone center during the show. This is a $35 value... and yes, it is for real (I pre-registered using this offer and have received my floor pass in the mail). I found this via Cubeowner.com. Before anyone asks: No, it does not include admission to the Keynote. Enjoy.
