Well, I am finally making my long-awaited move back to the East Coast. I need to ship about 75 rolls of film, and do not want to take them on the airplane with me. Most of it is right now either frozen or in the fridge. They are assorted chrome, print, coleor & B&W, and speed range from 64 to 1600. What method of shipping does not x-ray? Can I use the USPS Priority Mail, or is Fedex Ground better? Cost will be rather low, but I am most concerned about x-rays. Thanks for your recommendations!
