Check out the retailer's security safeguards. When making an online purchase, make sure that the retailer uses encryption or security technology to protect your credit card information. Indicators of security safeguards include a padlock or an unbroken key and are usually found in the corner of the web page. Secure your privacy. Know what type of information a retailer is collecting about you, how it is used and who it will be shared with.
Many retailers sell customer profiles to other retailers.
Determine if you can refuse to allow your personal information to be sold t other businesses or marketers. Be wary of sellers that ask for personal information that is not relevant to making a purchase such as your Social Security number, the name of your bank or your account number.
