Online business effectiveness and consumer attitudes toward online purchasing

I only need to extend my conclusion for my thesis, I have already written it with three pages but my supervisor asked me to extend it more. I have attached the conclusion and I made highlights by red colour where i want to extend the conclusion. There is a part in the conclusion requires mention some theories that i have missed to write in my conclusion. And I attached the theories chapter to write from. Please pick me a very good writer. Thanks
