Smash-up TV deals will be plentiful this Black Friday holiday season, but chances are you'll have to act quickly to be able to take full advantage of them.

USA Today labels a 50-inch flat screen slated to be offered for just $150 on Amazon starting November 26, as its top overall deal, highlighting it as the cheapest 50-inch set it's ever come across, some $90 less than the previous ceiling.

In-Store and Online TV Deals Available

Consumers will need to act quickly to be part of the mix, with both in-store and online bargains expected to move quickly. And in one high-profile case, the deal may only be offered via a mobile app.

That would be the aforementioned 50-inch, HDTV set being offered on Amazon.

"We'd never seen this before," said DealNews features editor Benjamin Glaser. "But as Amazon goes, so goes the industry. You may see other retailers throwing in mobile-only deals this week too."

Another deal that's almost certain to rate among the best is at Best Buy, where a 49-inch Toshiba HDTV will also be selling for just $150 in limited quantities. At Walmart, a 70-inch Vizio will be priced to move at just $898.

And Glaser expects prices to tumble even lower closer to the actual Black Friday holiday.

"You'll see retailers price match and undercut each other with live updates," he predicted.

Smartphones Among Biggest Deals

Smartphones also figure to rank among the best deals being offered, with Walmart offering a $250 gift card for the iPhone 6S, essentially knocking the price for the widely popular cell phones down to just $400.

At Staples, the Samsung Galaxy S6 with Verizon service is being discounted with up to $500 in credits.

"We weren't expecting any deals on smart-phones," Glaser said. "So this is a big surprise."

Tablets Priced to Move

Deals on tablets will also be plentiful, with Target offering a $150 gift card on the purchase of a $499 Apple iPad Air 2, bringing the effective price to $349. In addition, the Meijer iPad Mini 4 is priced to move at just $350 with the use of a $125 store credit.

The lowest priced bargain tablet of all is billed as the Amazon's 7-inch Fire tablet, priced at just $35.
