text: is ebay trading keeping the united states postal service alive?   ebay is certainly helping the usps. just take a look at the boxes the usps is offering to ebay customers:   http://freebies.about.com/gi/dynamic/offsite.htm?site=http://ebaysupplies.usps.com/  they have the ebay logo stamped on them! the usps would not be spending money to make special boxes if ebay were not making a signifcant positive impact on usps revenues.
