What not to buy in December
Looking for a high-end TV or a well-known brand? December is probably not the best time to shop, says Mendelsohn.
Expect better deals: You'll see some bargains after the holidays and right before Super Bowl Sunday, she says. Look for deals of about 25 percent off on the latest models, high-end technology and big-name brands, she says.
What is on sale: Lesser-known TV brands and more basic models, she says. And you can find deals of 30 percent to 40 percent off, Mendelsohn says.
