What should I add to my Amazon shopping cart for an upcoming vacation?

I am putting together an Amazon shopping cart for my vacation. Some of the things that are in there are Airborne, Goodies Powders, travel toothpaste, a bluetooth headset, an SD to micro-usb adapter, a couple of books. Of course I have lots of things already here but what would be some good things to take on a long trip that I could get from Amazon? My first question. I haven't seen much ATC-style chat here, testing the waters.
