Nice, I'm in! That regular retail edition gets me 2 versions on UHD and then one on BD and after tax and shipping was $1.91 more than the copy of Tombs of the Blind Dead that I recently ordered but this is a much, much better deal than that was. I hope this is going to be the way forward for Synapse, steelbook or not I want combo packs on these more expensive than average editions.
Both are $64.95 at the Synapse website, but I'm guessing Diabolik gets a [better] wholesale discount on the Benscoter cover since that will be a wide retail release.
