Website addresses that end in "org" are not for profit organizations. These sites contain information that is generally considered to be reliable. Planned Parenthood, the American Heart Association and the Salvation Army use this suffix.
Some organizations have biased opinions and information on their websites. While the data is accurate, it may not always include news or statistics that represent the opposing view. Always research to find out who is paying to own the domain name before purchasing any products from the site. Sponsors for these websites may have commercial intentions, trying to persuade visitors to buy their products over a competitor's products.
