As things stand, Black Friday is no longer confined to a one-day extravaganza. As early as last weekend, retail outlets are already introducing deals that will be available not just on the big day itself but also in the days leading up to Nov. 27. If you are looking to upgrade your television, here is the list of the available or announced Black Friday deals so far.

The Westinghouse 55-inch LED HDTV is unarguably the best deal at $250. The price point boasts a whopping $350 savings. It is the lowest-priced HDTV at this size and is available at Target or through this link.

Toshiba's HDTV is also an excellent alternative. With a slightly smaller display size of 49 inches, it will be sold for $150 and interested shoppers could head to Best Buy on Black Friday to buy one. 

The massive 60-inch Samsung UN60J6200 Smart HDTV will also be available for $698, $150 less than its retail price. It will be available on several retailers on Black Friday. The list of Samsung TV deals, specifically at Sears can be found in this link.

For consumers looking for an even bigger TV, the Vizio 70-inch TV will be sold for $898 during Wal-Mart's Black Friday sale. Early birds can also take advantage of the retailers "pre-Black Friday" online specials, which include discounted TV offerings.

Finally, there are retailers who are offering a different strategy that is also worth looking into. For instance, appliance store John Lewis is offering to match the competitor's prices on Black Friday. For more information, click here.
