I was all prepared to overnight a card this afternoon to SGC for their walk-through service when I was ready to type the shipping label and the only address SGC has is a post office box. Well as you may know UPS and FEDEX will not deliver to a post office box. It's ironic that on SGC's invoice they clearly state at the top that Fedex and UPS does not deliver to postoffice boxes, but they don't list their physical address to do the same. It was too late to call as their offices had already closed by the time so I was not able to ship it today. I was in a time constraint to get this card grades but since they couldn't at least put an address on their website I will probably just send it to another grading company.
