The game aisles at Kmart on Thursday were bustling with kids checking out each toy to make sure they didn’t miss a thing.

Most kids at the store were pretty sure they already knew what they wanted for the holidays.

“I want Legos,” J.T. Brand said.

J.T., 10, is in good company.

Legos are one of the 10 most wanted gifts for boys this year, according to a survey by the National Retail Federation.

Topping the federation’s list are video games for boys and Barbie dolls for girls.

But even with projections from retail experts, there’s no way to predict what’s going to fly off the shelves each holiday season, said Crystal Gonzales, merchandise manager at Kmart. “It’s hard to say just yet,” she said.

And there’s no way of stocking everything shoppers want.

“A lot of people coming in have been asking for items I don’t have,” Gonzales said.

But there are a few items she’s sure will be a hit this year. Disney princesses are always popular, and Kmart has a set that includes a doll, stroller and accessories.

Already, one new item, a computer pen, is a strong seller, she said. Used with special paper, the pen, called “FLY,” is billed as interactive. “That’s a big hit,” Gonzales said.

With FLY, a child could draw a calculator with the pen and solve a math problem with it. Plus, the pen can complete a task at a particular time and date and is programmed with a number of games and educational activities.

“They have a lot of new learning things for youngsters,” Gonzales said. “It’s all getting electronic.”

One example is the LeapPad Learning System, an interactive book that reads to kids, helps them learn letter sounds and involves them in games.

But when it comes to electronics, gaming systems still top the charts, Gonzales said. According to the federation’s survey, Play Station 2 is No. 10 on the boys list and Xbox ranks No. 6.

Gonzales said she witnessed its popularity firsthand Tuesday when the Xbox 360 was released. Kmart quickly sold out of the 24 systems on the store’s shelves.

And Gonzales said she suspects many other items will be cleared out of the store soon.
