I have to send some old magazines and photos to my publisher, for them to use in my next book. I offered them good copies or CD files, but, “we want to work from the originals.” And this time, they promised not to lose any (I am taking good copies myself before sending, just in case!).
Anyway, what is the safest way for me to send these halfway across the U.S.? Speed is not a factor, I don’t care how long it takes as long as they safely get there. U.S. Post? FedEx? UPS? 20 Mule-Team Borax?
