Affiliate makes consumers botherd

Before I buy something, books and digital camera, on the internet; for example, amazon.com, I will make sure and look into grapevine of those items on other web page. Then, it takes long time to search for useful information but the information always is link back to amazon.com. Finally, I am supposed to see same information of the site many times. Although affiliate program makes consumers bothered, I believe the affiliate is absolutely effective and contributes to sales.
