There are plenty of ways to maximize the savings Black Friday offers, says money-saving site Clark.com. Sign up for e-mail promotions at your favorite retailers before you head out to the stores, for example, and price-check items against the web while in stores. Make a list of the retailers you most want to visit and bring a friend who’s similarly motivated to find deals. But leave the kids at home if you want to do some serious shopping — you don’t need the distractions. Shop early or late to avoid the worst crowds, and above all, remember that not every low price is truly a deal.
