Where to find products, I've listed 3 of the biggest well known affiliate sites. They are free, simple to sign up to. There are no fees only commission on sales you make.
There are simply hundreds if not thousands of affiliate programs available. The more you look you'll notice when you are browsing on your usual internet shopping most large chains ie furniture and interior supplier's have an affiliate program.
Those sites normally require you to have proven traffic to either a blog or website. You can use social media websites if you've spent long hours writing and developing your online presence it shouldn't be difficult to get excepted.
This is where you can really use your passion to earn a side or full time income.
