It May Be a Good Time to Buy a Laptop If you are thinking about buying a new laptop, stop thinking and do it. At least that's what the algorithms at Decide.com say to do. Decide.com is a Web site created by artificial intelligence experts that tracks millions of price changes on consumer electronics and appliances and uses algorithms to to predict when buyers are most likely to get a deal. The site claims 77 percent accuracy since its inception in June 2011. Recently released data from the company showed that laptop prices tended to dip to seasonal lows three times a year: in late June, the last two weeks of September and beginning again in mid-December. The first dip would appear to be the back-to-school rush and the third comes after the Christmas rush. The second one, I don't know. But there are cycles in electronics when new products are introduced and old models retired. It is at those occasions - and they differ for different product categories - that shoppers can save money. Decide.com, which is also available as a mobile app, says its report is based on data collected from 116 sellers and on 3,600 models of laptops. The average savings was about 10 percent, with the highest savings at 30 percent, Decide.com said. Excluding high-priced game laptops, that should be an average savings of about $100.
