How it works?
Each time an affiliate link is clicked (all across the site), user will be redirected to the reseller page.
If a user purchases a product, you will get a commission.
One of the reasons affiliate programs are so popular is that that offer a win-win situation for both reseller and affiliate.
The reseller’s cost for advertising a particular product is limited (largely) to the percentage paid to an affiliate, and the reseller only has to pay when a purchase is actually made.
You don’t have to go to the trouble of setting up e-commerce functions, take credit cards, or ship products; you just join some affiliate programs and let someone else do the “dirty work.”
