Here, here! I would suggest ordering a new copy then returning the original for a refund. But then I'm still waiting for them to refund me for something I returned over 6 weeks ago (and they acknowledged receipt 5 weeks ago). I have now chased them about 4 times for the refund (which they keep saying will be processed in 3-5 days).
Another alternative might be to complain anyway and accept their usual offer of a 10% discount. That is what I have done whenever I have noticed some minor issues that don't seem worth the hassle of getting a replacement (or the item is sold out, so they have no copies left to do an exchange anyway). Occasionally, it has taken 2 or 3 replacement to get a decent, undamaged, copy ("Moon" was a classic example of that, as was "Close Encounters of The Third Kind").
Amazon are just on a different plane altogether. Whenever I have complained to them about inadequate packaging for steelbooks (e.g. when they have been sent in a standard A1 cardboard mailer), they have immediately given me a 20% discount regardless of whether the steelbook itself was actually damaged or not...
