err, I've had well over 500 quid cash back over the years for doing nothing more than clicking through a website before buying something I would be buying anyway? stuff like car insurance you can often get an extra 20-30 quid back after you have found the cheapest quote, mobile contracts are often even more lucrative... electronic stuff like TVs/fridges etc that I've bought having found the best deal often offer an extra 4-5%
seems a no brainer to me. Obviously some people have too much money to worry..
