There are two main parts of a Zazzle account that have the potential to earn money. One is the affiliate aspect, where anyone on Zazzle is allowed to advertise other people’s products. I believe you do have to add the affiliate part, but it is simple. The second is through royalties paid to the people who create the items that are sold. You can benefit from both of these simultaneously, and when your account reaches the fifty dollar threshold the money is forthcoming. You can spend your earnings earlier if you buy on Zazzle.
Zazzle income is passive income after the products are developed. Of course promotion, especially on a website or on Pinterest adds to your products’ exposure.
