I earn my living with a mail-order online business. The costs for picking & packaging are around 1-2%, even though we use a rather expensive option (a home for mentally disabled people). I just don't get why Amazon bothers with trying to shave off what, in total, cannot amount to more than 1/3 of 1% of its costs, considering how much these policies have cost them in bad PR, and, possibly, pangs of conscience. If they managed to reduce packaging material by 50%, they could easily double the salary of everyone in the warehouses, and still have enough over for all-you-can-snort blow at headquarter's x-mas party.
