First time submitting to CGC. I’m submitting 1 comic signed and another I want to get signed. I tried to combine the 2 but it’s not letting me. I see on the cgc cart that says 1 order can be open at a time. Also, when I googled the issue, it says I would have to submit 2 different forms. Wanted to know if this is true? Thanks in advance.
