I've ordered many, many times and always got my books in great condition. However, I must also say that I've never graded any of my books (but I do identify when there are folds, spine indentations or other minor details with the books).
For this Gamora cover I've heard that there are some complaints in how the books are being shipped now, so maybe you can also complain directly to their site.
I still have not received my copies, but will let you know how it goes. As I'm outside the US, maybe it'll take a month or so. =/
I got my Gamora's last week with the same results. I concur, that it was not a shipping problem. The books were packaged nicely and the box was not damaged. I don't think they guarantee 9.8 . IMO, it's just the way it is. The books were similar to an LCS comic that was on the rack for a few hours. Just light handling flaws.
