CGC has been doing some Twitter announcements and Facebook video Q&As with the signers. But I don't recall exactly when the actual signing dates are announced. So I've taken to checking CGC's social meda and sometimes, the creator's social media to get the actual signing dates. Finally your submissions are updated in the web "tracker" after they are signed and are put through the service(s) you signed up for. You can click on the links in the tracker to find out their grades before you open the packages.
Would I do this again? I actually have done it three times. I signed up and received my George Perez books. I'm waiting for two books from the Claremont signing, and one book from the Zeck signing. To me, it was close to a no brainer as the books tier value came close to the added cost of the signature. So my average cost is $100 a book with shipping/insurance. If my books are worth less than the signature cost, I dont have a strong emotional imperative to get a book signed. If they get Simonson to do a signing, they will get another book from me.
That being said, I'm gonna hang these on a wall when I get them back.
