I concur, I kept getting invoices emailed to me, but didn't really know why, thought it was just part of their process. I listed my credit card info to be charged on the
submission for just like every other grading company. After the 3rd invoice I called cust serv to find out why I keep getting emailed an invoice?? I was told
the credit card info doesnt transfer over in their system so I needed to give her my credit card info. That information would be helpful in the email. So I wasted 3+ weeks
thinking it was just "part of their process" She said the cards were already graded and would now go to the "slabbing room". That was roughly 3 weeks ago. My status is still "scheduled for grading" So if you get an invoice and you think
you already gave your CC info, you best call.
