Affiliate networks offer you access to multiple (and by multiple, we mean hundreds if not thousands) of individual affiliate programs. They basically work by simplifying the signup process - instead of applying to become an affiliate for a each product you want to promote, you simply apply to join the network and instantly have access to hundreds of different affiliate offers.
The best review sites (like BestReviews.com buy them all independently and test them without bias) but anyway, you could always review products you already own and use (recommended) or just not focus on product reviews at all, it's just one of 1000's of ways to make money as you should be able to see from the post that shares endless examples of ways people make money other than reviewing products.
If there’s no products on Amazon for “High end” then you have no Amazon products to promote and no way on earning any commission. Why not try keywords like Best (x) or Luxury (y) where there will be more search volume. Let’s say you want to promote hammocks, you can then target search KWs such as Best Hammock for Under $100, Most Comfortable Hammock, Luxury Hammocks etc. Let me know how you get on.
For the best results, you need to have your own website that contains the product or keyword you are promoting. For each product brought from your site you will earn a handsome commission. Additionally, very many people are registering with eBay. You will get around 25 to 35 bucks for every person who registers from your site. For advertising, you can use different tools such as creative tabs that have colorful graphics interactive ads that you can place on your website or blog you attract visitors to come to eBay pages.
In effect, VigLink works as the middleman between a publisher (blogger) and merchants by scanning the publisher’s content and automatically creating links to publishers that are chosen “in real time” based on their payout/conversation rates. This makes VigLink a very hands-off affiliate program for publishers who prefer to focus on content instead of managing their affiliate links.
“My beef with VigLink is that just because you’re accepted into VigLink does not mean you’re automatically accepted to promote all merchants affiliate with VigLink. You still need to apply individually to many merchants. This in my mind defeats the purpose and the main benefit of this type of affiliate service. Fortunately Skimlinks operates differently; once accepted into Skimlinks you can promote any merchant without further red tape.”

When do you want to get started? If you are just starting and have no audience then some of the programs may not accept your application to become an affiliate, while others will let you get set up in minutes. If you want to get started straight away then make sure you’re applying for programs that are less restrictive. Generally the larger, network style places will enable you to get going quickly while specific niche programs may require you to have a certain audience size or characteristics.
