Looking for a high-end TV or a well-known brand? December is probably not the best time to shop, says Hillary Mendelsohn, author of "thepurplebook" online shopping series and founder of ThePurpleBook.com.
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.
Want to get more mileage out of your money? If you travel for the holidays, have presents shipped to your destination "and avoid those checked-bag fees," she says.
