Your luck will run out with them one day, its not a matter of if, its a matter of when unfortunatley.
I think it's the same with most retailers though isn't it?
There's always the risk of damage in transit when something is posted to you. Add to that issues such as spine slashes (from both the retailer and distribution end), damage under J-cards from manufacturing (Evil Dead springs to mind) and general scuffing from wherever.
It also depends on your own personal tolerance in regards to what is acceptable and what isn't. For some, the slightest hairline 1mm scratch is the end of the world, for others a small ding on the back is neither here nor there. Obviously, we'd all love to receive a mint copy of our favourite films, but sadly, as with many mass-produced retail products not every one will be 100% up to scratch (excuse the term).
Just pick up 2 'identical' Star Wars figures, or 2 'identical' Bowen statues. No 2 are the same. Unfortunately, while the steelbook itself is often why we buy a certain title, they are just the box to put the disc in to most people. If I was to show some of the damage to my closest friends, they'd understand why I might be bothered (and to be fair, I'm not one that expects perfection), but personally they just roll their eyes and think 'whatever'.
My copy of The Crow has a very small (and I do mean very small) ding on the front. You really have to study it to find it, and hold it so the light reflects on the ding for it to show. Does that count as damage? To some I'm sure it does. While I guess I'd rather it wasn't there, it's slightly inevitable with anything made from such thin metal really.
