Swallow the loss. Keep it or sell it on.
The seller sold the item sealed. He did not know about any damages under the shrink wrap. You bought it from a private seller 2nd hand on ebay. You're entitled to get a replacement when you buy it first hand.
I know this sounds a bit harsh...
I really hope they will be showing the slips finishes & lenticulars before the pre-order goes live like they did before, since I'm having a really hard time to decide which one I want to get.
(Unfortunately the One Click or several editions aren't in the budget. :D)
Glad I'm done with HDZeta for the most part. Sure there are some exceptions, I'll do sometimes, but I won't bother too much with their boring flat steelbook DC Line. The only set I couldn't resist on was the TDK Trilogy. :)
