Just got these in for a promo we're having starting this Sunday. Apparently, the metalpak has a street date of 5/5/2015, yet my store hasn't received them until now. I'm kind of contemplating on selling my Mad Max Shout! Factory copy (as much as I dig the slipcover).
We'll also have Django, Wolverine, X-men, Terminator, and Commando steelbooks back in stock. I think the sale price for all of them is $11.99 each.
EDIT: A fellow poster corrected my error. It is a metalpak, not a steelbook. The other titles are being advertised as steelbooks, however.
