Total number of years I've been selling stuff on Zazzle: 8
Total earnings in those years: $30.20
In the several months that I've been an Amazon Associate I've generated a total revenue of $0.00.
Money from AdSense ads on this blog? Ha.
So far my earnings on Hub Pages have totaled $0.14.
I've done somewhat better with Heroic Portraits. With 4* customers - over the course of 5 years - I've generated a total income of $500.
However, that income is offset by the costs of server space and Domain Name registration. I don't think I'm in the negative numbers from that alone - I don't remember how much I've laid out for those expenses, but it's somewhat less than $500 - but if you factor in the cost of ink, paper, my large format printer, and my Wacom Cintiq, I'm seriously in the red.
*That's 4 paying customers. Total number of "customers" has actually been 7. Even a free Portrait promotion only got me 1 person willing to take me up on the offer.
