I believe Super Bowl weekend is THE best time to get a television. This weekend you may get some great deals, but usually just on a select few models.
Super Bowl weekend almost all televisions are on sale and the new models get announced in January so they are looking to clear out discontinued models.
If you can wait until then, thatís the time to do it. If not, I would look into a wholesale club to get a nice deal on a 4K.
