Amazon are relatively harmless, and do not force unwanted ads with obnoxious behavior on you. If you want to buy anything from Amazon, not just the stuff you may see in these ads, if you click on the ad to take you to Amazon, anything you end up buying generates a little bit of money (mostly of the order of a few cents). So next time you are going to buy something from Amazon, think about coming here first, and using one of the ads to take you to Amazon.
