The second decade of eCommerce will be marked by innovations that will make online shopping easier and more engaging. This will boost US online retail sales from $172 billion in 2005 to $329 billion in 2010, according to a new forecast by Forrester Research.
I don't have the 2007 numbers handy though, but 2005 63 million | Total Online Retail 172 million
63,000,000,000 / 172,000,000,000 = 0.36416184971098265895953757225434
so in 2005 it was 36.416% or every 36.5 cents of every dollar in 2005
