While cafe press is another way to make money online, it works pretty much like blogging. You have to continuously market and be unique.
You can sign up for free or sign up for a premium account for as low as $6.95 per month up to $59.95 for 1 year. Cafe Press Premium members get to fully customize their store's look and feel and a bunch of other stuff like featured product section, categories, newsletters and more.
I will probably put more attention on my cafe press shop once I'm done with my other stuff. If you're curious, you can visit my cafe press store here.
