This domain looks like it was registered on 18/09/2010. Could you explain where the revenue comes from? I noticed the site is just a sedo parking page, with a link to it from an expired ebay listing advertising vouchers?
It earns the money from people clicking on the ads on the Sedo parking page. At a guess I would say the traffic is type in traffic, for people looking for the 'love2shop' highstreet vouchers - I am sure Laura will clarify though
