Someone can correct me if I am wrong but thepit.com only tracks sales of cards sold on their site. They are another online consignment store similar to COMC and they don't come close to the market coverage that eBay does, which is the source of our sales statistics.
I'll reiterate what diakonos more or less has said. COMC could be something we add to the equation in the future but for the true movers and shakers, COMC for the most part does not contain what we classify. COMC is a great place to get things in bulk and harder to find cards for sets but not...
We truly appreciate all support from the hobby community and hope we can just keep everyone informed and up to date on prices. diakonos and I are hardcore collectors and love the hobby so we hope to be around for the long haul!
