Jem, the newest and third-largest suburban mall here, finally opened its doors on Saturday morning after having been mired in a four-day delay.

But it was a case of better late than never with some people arriving as early as the night before, camping overnight in a bid to secure store promotions throughout the 818,000 sq ft of retail space that is home to 241 shops, including big brand names such as Marks & Spencer, Sephora and Topshop/Topman.

Lines were also seen wrapping around the new Jurong mall's main entrance from 6am, where more patrons jostled to be among the first thousand to enter and be eligible for limited $10 shopping vouchers.

All 1,000 vouchers were given out in less than an hour from the 10am opening, during which more than 10,000 shoppers passed through the mall's doors, a spokesman for Jem reported. By 4pm, that figure had jumped to nearly 50,000, said Jem development director Chris Brown.
