Amazon's packing skills have lead me to order in batches that I think will ship well together. Once I see that heavy item that is going to pound and smash the other items has shipped I'll order the rest. It is less than ideal, but as long as they suck at packing they can deal with two orders instead.
Only, you have to space your orders -- wait at least a day in between making them. Otherwise, their system often combines them and you end up with one box, anyway.
Kind of defeats the quick delivery convenience/reputation they are after.
