1) Put away your cell phone while shopping. Use an old fashioned pen and paper. Not only are you distracted but you hold in your hand a "magic box" worth hundreds of Benjamins!
2) Make sure you zip your purse completely shut before leaving your vehicle. If you carry a wallet, carry it in your front pocket.
3) Your car Fob is not your Friend..parking in crowded parking lots and leaving your vehicle for long periods of time, you can be at risk for theft. Thieves can capture the signal from your Fob to your vehicle and "shop" in your vehicle while you are shopping. Manually lock your car doors.
