Well, my submission was finally processed, but I was a bit disappointed in the notification:
We finished processing your shipment of 77 cards. 15 cards are being returned, and 62 cards have been added to your 'DaClyde' account. $12.30 of your store credit was used to cover the processing fee.
I replied asking of COMC's licensing deal with Beckett is somehow exclusive, precluding them from using any OTHER resources for checklists and pricing. I'm guessing most of what is coming back to me is Japanese or oddballs that SCD lists but Beckett ignores.
Then there's the matter of my having sent in 85 cards in that submission....
