3) Tape Runner -- this is how I attach the paper to the inside of the box. Anything else just takes far too long. You can get 2 for $2.50 at Wal-Mart and it takes about 1 to cover the entire inside of a box.
4) Obviously, you need boxes. I ordered in bulk at the start of the deployment and have loved having the boxes handy whenever I needed them. You can get them on the USPS website FOR FREE, so I highly recommend ordering a bunch.
5) Tape -- other obvious item. I like my pink tape dispenser (not that it really matters). I do recommend heavy duty, but don't buy the kind at the post office -- you can get it much cheaper at Target or Wal-Mart.
6) Customs Forms -- It is infinitely easier (for me, anyway) to fill the forms out online and print the copies. This way, they're filled out, signed, and ready to go when I head to the post office. It cuts down on the wait time. And if you fill out the online version, you can fit five lines of items instead of four!
