Wizard often featured mail-away offers for exclusive merchandise. Wizard began a practice of producing specially offered Wizard #½ issues. These were special issues of ongoing major comic book series which featured in-continuity stories that supplemented the regular series’ published issues. The issues were numbered #½ so as not to disrupt the series’ ongoing numbering system. Often Wizard would also include free pack-in issues with their magazines, usually numbered as Wizard #0.
