Shopping can be a dangerous game.

• Position: Security - Holiday shopping

Consumers are expected to spend 3.9% more money on holiday shopping this year than last, according to the National Retail Federation. Such consumer optimism also may mean that holiday shoppers are feeling the competitive spirit--battling busy stores and hunting down aggressive deals--and unintentionally pulling their personal safety at risk as a result.

"While big holiday shopping outings have become a tradition for many holiday shoppers, we encourage everyone to remain vigilantly aware of their surroundings," advises Sean Lomonaco, owner of Signal 88 Security, Kings Park, N.Y., a private security company with more than 100 franchises throughout the U.S. and Canada.

Lomonaco offers the following advice to consumers:

Practice patience. Often, long lines can lead to short tempers. When store doors open, proceed with caution, and avoid running or pushing. Same goes for standing in long checkout lines; expect to encounter potentially frustrating delays.

Stand guard. Inside a store, never leave your purse, wallet, or shopping cart unattended. Also, be mindful of security threats in parking lots. Always keep your vehicle locked and your purchases out of sight. You can enlist the assistance of store security if you feel uncomfortable...
