I still don't understand people trying to sell something that is already FREE.
Doesn't make any sense anymore.
If you are wondering why your sites aren't selling anymore, just visit this link:

Now, look to the right, and click on that sun star and change your safe search settings to OFF.
Then, type in any filthy, nasty disgusting phrase you can think of, and BING will deliver you tons and tons of clear, beautiful porn video at your fingertips for FREEEEEEE!!!!!
That's why your sites are not selling.
It's not your fault, it's the hundreds of thousands of morons in this business that thought free samples were the way to go.
That thinking as ruined the business model FOREVER.
Get over it already and go hang out with the day workers at Home Depot. You'll get some much needed sun and exercise and you will make more money working, than sitting around bitching about not being able to sell something that is already free.
