I clicked on a number of products to see where it took me. It does appear that the products are connected to Amazon but one would never know it since the product that shows is not the same as the listing on Amazon.. I have started a site using Amazon Affiliate products and when a visitor clicks on a product on my site it takes them to the product listing on Amazon which looks totally differenet than the Gear Patrol listings.
In addition, you must know how much you want to earn by joining affiliate programs. Will it be your main source of income or just an additional one? For the first scenario, you should consider promoting products that are expensive and, consequently, that can bring you a good profit. If you plan on the second scenario, you can opt for affiliate programs that pay for sign ups or affiliate programs that pay daily.
