A URL is the online equivalent to a company's physical address. Scammers cannot duplicate a legitimate company's URL, but they can come very close. By typing in the URL of the company you are checking, you can find out who registered the URL and the person or company's address. Protect your privacy. Provide personal information only if you know who's collecting it, why, and how it's going to be used.
Many online retailers post their privacy policy somewhere on their web site.
Reading the policy allows you to make an informed decision about what information you want to provide. Guard your passwords. Use different passwords when you're making a purchase than you use to log on to your computer or network. Avoid making your passwords established numbers like your house, phone, or birth date. Determine the company's refund and return policies before you order.
