The economy's shot in the arm has already taken effect, as scores of shoppers across Colorado flock to stores early this morning in hopes of getting the best deals on the biggest holiday shopping day of the year. But Edgar Dworsky, founder of ConsumerWorld.org, a noncommercial consumer-resource guide, tells The Denver Post consumers might be smarter to wait and make some comparisons online before they flood the aisles looking for deals. Early ads show some of the best deals are for electronics---from digital cameras to flat-panel televisions, writes 7News. Consulting firm Accenture predicts about 52 percent of American consumers will shop today, up significantly from last year. But it isn't clear whether the momentum will last. A big turnout might signal consumers' desire for a deal rather than pent-up demand, The Washington Post points out. One trend: Shoppers are less likely to use a credit card, and many are turning to layaway in an effort to prevent rising interest rates from dampening their fun in 2010, reports 9News.
