Maybe that is just for dealers ?
The email I received only had the following information:
As CGC continues to increase the number of comic books and other collectibles it grades, it is no longer able to allow Collectors Society members to pick up their collectibles at the CGC headquarters in Sarasota, Florida. This change is effective for all submissions dropped off, postmarked or made at a show after September 10, 2018.This change is due to costs and logistics, including space limitations at CGC headquarters. Members should ensure that their shipping information is included on the online submission form so that collectibles can be shipped back, as the overwhelming majority of submissions already are.Collectors Society members can continue to drop off their submissions at the CGC headquarters, as well as the dozens of shows that CGC staff attend annually.
