Look inside your vehicle before entering it, and examine it for any intruders before entering. Once inside your car, close all the windows and lock all doors. Try not to leave items bought in one store inside the car, while you go to another to shop for something else. Remember that if the car is broken into, you will not lose as many items. Never send money orders, checks, or wire money to anyone you don't know, or in exchange for a prize.
Chances are it's a scam.
As you leave your home, make sure all windows and door are locked. Do not expose your items to the public eye through the windows at home. If your home is equipped with an alarm system, activate it as you leave. You need to have two sets of keys. When walking, avoid walking close to shrubs and trees.
