I`m  writing a diploma on e-commerce in europe but i have difficulties finding statistical information (charts,tables...)  for previous years (2006,2005,2004...), I found some statistics for USA (http://www.census.gov/mrts/www/data/html/07Q3.html) and i would need similar data or any data on e-commerce for european countries. I know there are some studies made but i dont have 700 and more eur to buy them, so if someone has some useful links, i would be very grateful if you posted them. Thank you!
