content: Since the Amazon market place works just like Ebay. I think that the issue I you're having is not due to Amazon themselves but rather due to people having figured ways to game the system. How would it serve their interest to sell you the cheaper version of a product when there is a more expensive version and thus a greater percentage for them?  Your complaint is basically that they keep directing you to whoever sells some widget the cheapest. Which doesn't really sound like a problem and is probally more down to the fact that if people are going to buy something they're naturally going to get it at the cheapest possible price.
