I have to agree that the the turnaround times are not up to par. I also paid the express fee for 2 days when I submitted my coins. It took way longer than that--no notification, no message, and didn't even ship it express back. They charged me right away though!!! I pretty much got taken advantage of with the prices. I paid an express fee for a modern service basically. Nothing is updated on the website. "Turnaround times are not guaranteed" is not to mean that 2 days turns into 10. It means 2 days turns into 4 max, with a message or some sort of compensation.
I urge anyone submitting to not request or pay for expedited service because you are not getting expedited service.
