I've seen many people selling products online, like ebook "Where Winners Live", in amzon This ebook prices $13.80,
but when I open google . com, and search with keyword "free download ebook here Winners Live" many blog share it, and I get it free,

Someone buys the product and shares it or the seller may be dumb enough to not protect the location of the files.
