You love the Friday-after-Thanksgiving sales—and so do more than 140 million other people, according to the National Retail Federation. To make the most of the bargains:

Have a game plan. Avoid overspending by bringing a list of the people you want to shop for and the most you want to spend on each. 

Comparison shop. Cell phone price-comparison search tools such as Frucall, which operates via a toll-free number, can help you find out without leaving the store if you’re getting the best deal in town.

Shop online. Many retailers offer Internet-only deals. Check out the retailer sale ads online at sites like Black Friday Ads (bfads.net).
