When is buying a new TV an investment?
Compared to the going rate for tickets to the Super Bowl, buying a set that makes you feel like you're there can seem like the better deal.
Average Super Bowl ticket prices have fallen to $3,019.99 as of Monday, according to ticket broker TiqIQ. They could go lower before kickoff. But for that price, a shopper could go home with a 55-inch 4K Ultra HD set that has 3-D and Web connectivity that will last several football seasons. (Plus, with forecasts calling for cold temperatures and the possibility of rain or snow, the opportunity to watch in comfort.)
The savings come because experts put current deals 5 percent to 10 percent better than at other points in the year, even beating out some Black Friday deals. And yes, the ultrahigh-definition 4Ks are among sets on sale at Amazon, Best Buy and other retailers, in some cases as much as 20 percent off. Other high-def sets are discounted by as much as 40 percent.

But this time of year is also when retailers start to clear shelves to make way for new models. So read reviews to make sure you're buying a bargain rather than a set that will be outdated before the next Super Bowl comes around.
