I wanted to buy David DeAngelo stuff, but found it for download.
Then I wanted to buy a body workout program, but found it for download.
Then I bought some info for how to get a free iphone, and it told me to send them a brick basically, I didn't get an iphone, didn't try it, and lost my money.
It's better to sell info than to buy info. Though best info is free for you to download, just look for it.
