I need to ship an 11x14 mounted on a 16x20 board. I might wish to ship a 16x20 frame with it if it doesn't increase the costs of shipping it drastically. I was going to just take it, sandwiched in cardboard, into the FedexKinkos store and let them box it and ship it, but my customer lives in rural WY and has a PO box. This leaves USPS, which I have sworn off a long time ago, and last I heard they would not ship frames with glass in them. Anyway, how do you ship mounted/matted or framed photographs?
