Ebay... an unconfirmed rumor....
I had heard that for the year 1999 5% of United Parcel Service's
residential business was due to Ebay.
Gotta be a higher number at the post office. I talk to other ebay sellers
about every time I go, and lots of them have a big stack of priority mail
boxes. ALL the post office tellers are on eBay at one post office I go to
and when I hit that last in line after 5 PM we often talk shop.
