@Jez123: the Google CSE results you've mentioned must have been query or niche-specific. I am seeing the same crappy Amazon-dominated results (#1 plus two or three more on the first page although not a solid block) that they were around back in October-November 2012. Some of the queries which are nearly impossible to interpret as an intent to buy are Amazon-free but anything that includes a product name or just anything at all that has ever been sold, I see Amazon still *very* prominently featured.
The irony of course is that Amazon does not need Google to boost their sales - I imagine most people simply go straight to Amazon and start their shopping there.
