The link to the "non-store" download page which we tell everyone about is: http://continuum.io/downloads.
Yes, we are a company and do sell things, but our commitment to open source is backed by many, many years of significant contributions to the community. We give as much away as we can, and sell to those who need more.
While you certainly buy more from us, Anaconda itself will always be free as long as we can continue to make it.
