Would you like a months worth of free stuff via? Or six months worth of free Comic Con Boxes? Here is a flip idea.
Comic Con Box, the subscription box service from Wizard World (they say it is a premium box subscription service, or a con in a box), has a Batman Adventures #12 Comic Con Box Variant in it. The Box costs $29.99 plus shipping. The Batman Adventures #12 Comic Con Box Variant is selling for $54 online. Buy the box. List the Book. Make a profit. And keep all the other goodies in the box.
If you do a 6 month subscription at $179, you get the Batman Adventures #12 Comic Con Box Variant plus a Batman Adventures #12 Black and White Comic Con Box Variant. The Batman Adventures #12 Black and White Comic Con Box Variant is currently listed at $149.00. Add that in with the color variant selling at $54 and you are looking at $203, well above the $179 cost plus you get to keep (or sell) the other stuff from the six months worth of boxes.
