backdraft, i think about following. When g* does anyway show amazon for every query in frist 3 positons, why not advertise on amazon dirclectly, instead doing adwords with google? You know all traffic goes this way from g*, so why use g* as a third party tool, when we can have the first party tool? 10 million real buyers instead of g* manipulated personal search zombies ! I think about it and will probably give it a try.
