What can you say about e-commerce? (Online banking, shopping, auctions etc)? -

I m doing ICT homework about online services and I have chosen to write about e-commerce.Can you just provide me with any information you know about this in either bullet point or links or your own words?And also could you name any other types of commerce than what I stated in the question? Thanks for any help.

well online shopping is the best portal that you can get very easily if you make a search at google. however you can check the working of shopping sites like http://www.wwhow.com/ and i am sure that you will be benefited from it.
