Ebusiness Dissertation / Theseis

Ok, well its my final uni year and I have decided to do a dissertation (10,000 essay) on:

“A comparison of Tesco’s e-business strategy in relation to that of their competitors and an evaluation of the factors that have led to Tesco becoming the worlds leading online grocery store.”

however I have found it quite difficult to find any information on it so far.

I was wondering if anybody had done a similar dissertation that I could buy from them?

Also I heard there were some ** Online Stores Only ** some of which shut down. I would be very interested if anybody knows what these were or where I could get information on these.

ty for looking & any help offered.

dissertationwriters.com would do it for me but it would cost me $750 !
