I recently bought a couple of bows that had to be shipped to me, and witnessed both an excellent and horrible packing job.
The first bow arrived in a long rectangular postage box, with both ends of the limbs thoroughly padded in bubble wrap and the rest of the empty space so packed to the gills with crumpled up newspapers that the bow was suspended in a nice cushion. The bow came to me undamaged, and I gave the guy an excellent review.
The second bow I ordered also came to me in a long rectangular box, along with a custom "bonus" bow of the same make and model. Unfortunately, both of the bows had been bound together at the ends with a couple measly scraps of bubble wrap, and had been rattling around in the box (chipping bits of finish off each other) during their entire journey. Granted, they're both still shootable - but still. That's not acceptable.
