Tracking for sales on Mercari

This is something I've suggested as well, and don't know if I'm the first, but I can yell you that I received a reply saying PriceCharting was reaching out to Mercari to see if they could do just that. I'm not aware of any progress or hurdles yet may have encountered, but I was very happy to know PC has listened to our requests and is doing what they can to make it happen. This will likely be closed as a duplicate request, but wanted to assure you that someone was trying for us.
