That's a shame, I have always gotten really nice boxes and the best packaging from RK. Unfortunately no-one guarantees box condition except for say BBTS when you pay extra for collectors grade.
I ordered doubles of Dirge from RK in May just before it was released and requested mint boxes. They actually emailed me to say they couldn't guarantee this and asked was I ok to continue the order on that basis. I said yes and it all worked out ok. It seems like given it is now August, they have a lower inventory and so the boxes are less likely to be minty. Unfortunately this is another side effect of the PC bungle where we all had to scramble to order elsewhere.
