If you are shopping online, be sure to use a secure browser. Keep your personal information private and shop with companies you know are reputable. Do not give out your Social Security number, e-mail address, telephone number or address unless you know who is collecting the information and how they will use it. Save all transaction information, including e-mails and records of any phone conversations.
If you are dining out, valet parking is nice, but don't be too lax. Don't leave any personal items or your garage door opener in your vehicle and NEVER leave your house key with the attendant. Give them only the key they will need to park your vehicle.
