Any suggestions for shipping a windshield?

[scoobydrvr]

My car has a big, poorly-repaired crack running from top to bottom on the drivers side. I found a replacement windshield (bronze tinted and everything!) but neither the seller nor myself have any idea how to ship the dumb thing. Has anyone done this before? Suggestions for packing and shipping company? Normally I'd try to pick it up locally but I can't make the 18-hour drive anytime soon.
