Need to show the growth over a number of years 5) Growth in online product sales. Looking to try and compare the growth in online retailing vs traditional shopping centre retailing 6) Growth in deals sites such as groupon and other sites Other online states showing the rise in people spending money online are sought as well during the research phase. Any graphics would be great however the data doesnt need to be pretty. Screen shots from sites are fine. Each statistic needs to be reliable and each have a reference to the source reference
