The National Retail Federation says almost one hundred forty million Americans are expected to shop this weekend. Many stores have advertised reduced prices and expanded shopping hours.

So what will shoppers be buying? Experts say small collectible objects are hot items for children this year. The Fisher-Price Sing-a-ma-jigs are an example. These soft, brightly colored characters make music. But you have to make the beat by squeezing them. They make funny noises and can sing with other Sing-a-ma-jigs. Each costs about fifteen dollars.

Paper Jamz are also expected to be popular. These are paper-thin musical instruments. Inside are battery-operated devices that are very sensitive to touch.

Paper Jamz come with three songs built in and four ways to play the instrument. You can use the "freestyle" play and create all your own songs. Or you can use "perfect play" and out will come a hit song exactly as recorded by the artist. You can even play it with vocals or without. Paperjamz are made by WowWee and cost about twenty dollars.

The National Retail Federation says adults are interested in different presents this year. The industry says useful gifts like pots and pans, toasters and tools were popular last year. This year people will be buying jewelry and personal care items.
