Gone in a Flash...

Four days. That's how much time New Yorkers had to get a piece of the upscale design line Proenza Schouler at discount prices. On Feb. 2, the über-chic discount retail store Target (TGT) popped open a store in lower Manhattan, to display this latest high-fashion-at-low-prices design line. The store then closed on Feb. 5.

In a world of BlackBerries and instant messaging, there's a growing sense of haste in people's lives. In response, companies trying to get consumers' attention are trying to create a sense of urgency. For retailers, who need to get people into stores to try out their clothes, their shoes, and any other new products, the store itself is the new limited edition. So limited in fact that it may last a mere 96 hours. "There's a certain passion about things that shout 'act now!' and that has transpired into the way we shop too," says Claudine Gumbel, co-founder of Think PR, a New York fashion publicity firm.

These days, retailers are adopting the concept of a pop-up store with gusto. A pop-up store opens up at an empty retail location for a few days in a major city, or a mall, with great fanfare. And then, poof! It's gone. Last year, in November, Nike (NKE) opened a pop-up store in Soho for just four days for the sole purpose of selling 250 pairs of the Zoom LeBron IV NYC basketball shoes, named after the popular 22-year-old NBA All-Star LeBron James. The special edition shoes were priced at $250 each.

In May and June, Gap (GPS) kicked off a '60s style tour, where it used a school bus as a traveling pop-up store that made appearances in Los Angeles and New York and stopped at beaches on both coasts. Instead of seats, the bus sported shelves filled with t-shirts, flip-flops, and beach hats that people bought and paid for at a cash register near the driver's seat. Even the stodgy giant Wal-Mart (WMT) adopted the concept last April, when it showed its new fashion line Metro 7 in a Fashion Cabana in Miami's South Beach district, open for only two days.

BUDGET BUZZ

Retailers use pop-up stores to generate buzz and excitement around a new product launch, as in the case of Target's Proenza Schouler line. Sometimes, the stores are a great way for stores to check the pulse of consumers and try out new products. Usually, they are less costly than television ads, which can run in the millions of dollars to produce and broadcast, and the stores generate similar buzz and publicity for new brands.

Even nonretailers are giving it a try. The U.S. Potato Board, which represents American potato growers, opened a pop-up store in New York, during the week of Thanksgiving, for less than $200,000. The group, with the help of cartoon character Mr. Potato Head, promoted the message that potatoes contain more potassium than bananas as well as nutrients like folic acid and vitamin C.

"We were featured in The New York Times, in the network morning shows, and in many places," says Amy Kull, senior vice-president at communications firm Fleishman-Hillard. "We could never have bought that much media within that budget."
