Zazzle is a fun way to make money on the internet. It allows people to be creative in a number of ways, and make money from sales. But, the person has no problem with shipping, nor with warehousing a large inventory. Zazzle handles this for you, and even handles the sales. Oh, you are allowed to advertise products yourself, but Zazzle does as well, and right now it is a good income maker.
The amount of money you make depends on the number of products you have, and on visibility of your products. The more products you make, the better. And, sometimes adding an image to a multitude of products may seem a waste of time since certain objects look like they might not sell, but surprises happen and many do sell.
Getting visibility on Zazzle with their many designers takes time, and sales seem to push items up, but so does Twitter. After you make a product, advertise it on Twitter, G+, Facebook, and especially on Pinterest.
When I started on Zazzle there was a small, but nice, selection of products available. Now, the offerings are much greater. The only problem is that new products may not automatically be added to old designs, so as you get notice of something new it is a good idea to go back and add your designs to it if the design works for the item.
The introduction is one of my Zazzle products.
