Radio Shack, Sears, Staples -- just a few of the retail chains that are shedding hundreds of stores, as the face of retailing changes and online buying and selling gains momentum.

Some suggest the struggles and eventual closings of some shopping malls are sounding a death knell for brick-and-mortar stores.

"I don't know that we're at that point," said Dr. Carol Kaufman-Scarborough, professor of marketing at Rutgers School of Business--Camden, "but I believe it's certainly the call to streamline and develop new strategies."

The preponderance and growth of online retailing has certainly changed the way people shop, according to Kaufman-Scarborough. She said the relatively small amount of time it takes to browse a website has cut down, to some degree, on consumers venturing out to individual stores.

While shopping at a brick-and-mortar, will the consumer look at an item and then shop elsewhere, or online, to make the actual purchase? That is a strategy that the retailer can try to control. Malls may even have to shift gears in their choice of so-called "anchor stores."

"Having a mall that would be anchored by other very popular stores, that are a combination of stores, may be a way to increase patronage," Kaufman-Scarborough said.

She suggests another idea is placing new and different big-box stores in close proximity to malls.
