The most I have earned online so far was at xmas. Everybody was after the Nintendo Wii and nobody could get them but there were some for sale on Ebay. so I threw a webpage togeather and in the middle of the page I placed a great big Ebay affiliate rss feed. Then I advertised the webpage on google adwords stating Nintendo wii's for sale. I had massive traffic and plenty of commision sales. It seems that everyone these days are after a niche. What about this, the most sought after children's books at the moment are by the author Stephenie Meyer. Parent's will do anything to keep there child happy. Why not try something similar to what I did with the Nintendo Wii.
