Has anyone worked with Fanatics Authentics and had their items signed via mail order for one of their shows?

I have a couple of high end items I would like to get signed but can not make it to the show as it is out of state for me. They have an upcoming show in Chicago in which they are accepting mail orders and I was wondering if anyone had any positive or negative feedback on how their communication was and how the signing went. Thanks in advance for any input!
