Just in the for the Holidays, the Fan Expo Store is offering a true Convention in a Box Mystery Box.
These cannot be ordered from the site. You had to be on their mailing list to get the offer for the Mystery Boxes, however, if you want to order the standard box you can click here and for the premium box click here. (The links do take you directly to PayPal, Fan Expo Store’s not mine)
The Color Bruce Timm Variant sells for as much as $29 by itself ($20-$24 range mostly), the Black and White Variant sells for just as much. The Virgin Black and White in the Premium Box is limited to 500 copies.
The boxes are limited to 1 per customer.
