How would you guys recommend packing a pcb, however? I have never had to ship one before, but it would be nice for future reference.
Well, for starters, I'd use some actual packaging material... It's not hard to safely ship a board - the only problem is that you need an IQ greater than that of bubble wrap in order to do so.
Put the board in an anti-static bag (cut and tape a couple small ones together if you have to). Tape it closed. Then wrap the board in a couple of layers of bubble wrap, and package into a box that's big enough to provide at least an inch or two of cushioning on all sides, but not so big that the thing bounces around. Make sure you've got enough bubble wrap on the ends and corners to prevent the board from getting pounded into the sides of the box, and so the board is secure and won't slide around in the box.
If it's a multi-board stack like Pole Position or Donkey Kong, then put cardboard or something between the boards so they can't flex down and bend or scrape against each other. If the boards are vastly different sizes, like a Golden Tee boardset with that little video card, then each board really should probably be wrapped seperately.
If you're shipping multiple different boards in one box, you should really wrap each one seperately, or at the very least put cardboard between them. Never stack boards "naked" in a box - they'll gouge each other up and arrive with broken chips, sliced traces, etc.
