Digital River

I was impressed with lecture of Brent Mori and I’m honored to have him as a graduate of IUJ. I think that Digital River’s differentiation from big competitor like Rakuten is very clear. It's business model which their profit comes from fee proportional to the customer’s sales revenue is also very good theoretically. But it's business faces some difficulties in Japan. I also have seen the Degital River's HP or some article about it, but I could not find its shortcomings. I felt need to examine Digital River’s business in detail such as pricing policy etc. and competetors.
