I asked CGC the exact same thing as I have about 10 or 12 books at CCS waiting to pressed so it'll be several months before they even get to grading....unfortunately they told me that they will not change the invoice once the book is in house, so I'm out of luck getting the new labels...and I'm not going to pay a reholdering fee, and 5 handling fee, and 5 Spidey label fee, plus shipping when the books are still there for several more months. Sucks, big time, but what can you do. It's cleaner and easier for them, and it's their yard.
