Skip the Crowds: Online Shopping Tips for Black Friday

You probably already know that many Black Friday bargains are available online too. Save the Kevlar vest for another day. Rather than brave the elements or risk being trampled at 5 a.m., it's much more pleasant to shop from the comfort of home. We asked a few expert bargain-hunters how online shoppers can score the best deals on Black Friday.

Retailers often say they won't sell doorbusters online, but that's not always true. Here's their advice: Dan de Grandpre, editor in chief of dealnews: Doorbusters, those incredibly cheap deals designed to get people in the door, may be available online too. Last year, for instance, Wal-Mart offered all of its doorbusters online-but not until later in the day on Friday. Many Black Friday deals aren't in fact great deals. Don't give up the savvy shopping techniques you'd use all year just because it's Black Friday.

You'll find better prices online. Michael Brim, president of Black Friday deal site BFAds : Some retailers jump the gun and start their online sales as early as midday Thanksgiving. Use price-comparison sites like PriceGrabber and Shopping.com to be sure you're getting the best deal. Yes, while you're eating. (You could always excuse yourself from the table to nab that $78 Blu-ray player.) Then again, many sales start between midnight and 3 a.m. (Eastern) on Friday. Be aggressive.

If you have trouble staying up, try a quick nap after dinner. You can't wake up at noon Friday and expect everything to be in stock. Well, you could reload a retailer's page for hours. How do you know when online sale goes live? Another option is to monitor Black Friday sites like BFAds. John Dunkin, founder of iBlackFriday.com: Plan ahead.

They'll let you know when sales are live. Go to a retailer's site early, pick out everything you want, and add it to your shopping cart. You can get pretty much everything you want online. Next, log into your account on Thanksgiving Day to see if your products are available at Black Friday prices. If you don't need a doorbuster item, don't bother going to the brick-and-mortar store.
