I use Millers for all of my printing needs. I try to meet most of my clients to deliver their prints but sometimes I will mail them. VERY CAREFULLY! I use a bubble envelope with cardboard and the foam that comes with my Miller's order. It works, but doesn't look so professional. How do you present/package your prints when deliving them to your client, either via mail or in person? Do you have special sleeves? I wouldn't even know where to look for something like that!
