"Amazon.com Inc. said late today that its fourth-quarter global shipping costs soared to $5.6 billion, as the Seattle-based e-tailing giant grappled with increases in fulfillment demand brought on by another peak-season quarter of double-digit sales growth.
At the same time, fourth-quarter global shipping revenue came in at slightly more than $3 billion, continuing Seattle-based Amazon's multi-year pattern of shipping costs exceeding revenue. For the year, Amazon spent about $16 billion on shipping services and took in about $9 billion in revenue."
