I am about to move and even though I sent my coins in to be graded via registered priority mail, it still took four days. So, I asked my mail person how long registered mail generally takes and they said it could take up to twenty days.

Does anyone have advice on this. I've already paid for Express grading service for my first six coins (inherited a huge non-graded collection) however, I really didn't think much about the mails turnaround times and marked registered mail for the return route. Should I get a hold of NGC and have them change that to Fedex since my coins probably won't be done until Monday AM? I live in California and they're in Florida and I'm supposed to be on a truck and moving on July 27th and would hate for the people who bought our house to get the coins. I would love any advice!
