At Toys "R" Us, the doors open at 5 p.m. Thanksgiving Day. Many of the best deals are only available on certain hours and supplies may be limited.
Wal-Mart shoppers can snag rock-bottom prices beginning at 6 p.m. Thursday and the retailer is offering one of the best Black Friday deals on an HDTV set. A 32-inch LED model from Funai is on sale for just $98.
For an even better deal on a much bigger set, Target is selling a 50-inch Element HD television for $229 on Black Friday. The store usually sells it for $600.
Samsung's Galaxy S4 is one of the top-selling smartphones. Verizon sells it for $199 with a two-year contract. But you can get the exact phone at Staples this Friday for just one penny with the same two-year contract from Verizon.
K-Mart gets the jump start on its competitors, opening its doors at 6 a.m. Thanksgiving morning. One of its signature deals is a seven-inch Mach Speed android tablet for $39.
Apple products are always in high demand over the holiday season, but you rarely find discounts. The 16 GB iPad Mini retails for $299. Wal-Mart is selling it at the same price, but you also get a $100 Wal-Mart gift card.
Target is discounting the 16 GB iPad Air Wi-Fi by $20 at $479, plus you get a $100 Target gift card.
If you're interested in an iPad 2, the founder of the Black Friday deals website, BFAds.net told us via Skype that another retailer is passing on the savings instantly.
"This year, we actually see Best Buy just take a straight 25 percent discount off the Apple iPad 2. Normally it retails for $400. You can get it out the door at Best Buy for $300," said Michael Brim with BFAds.net.
Also at Best Buy, is the GoPro HD Hero 3 camera for $249, an $80 savings.
And gamers will save big on Nintendo's popular 3DS XL system. It retails at Target for $199; on Black Friday, it's on sale for $149 -- Target's lowest price ever on the handheld game.
A previous generation Kindle Fire HD 7-inch tablet sells for about $169. But you get a much better deal from Best Buy: $99 for the same tablet. The deal starts at 6 p.m. on Thanksgiving.
And at Amazon, you can find new Black Friday deals every 10 minutes all week long. Other online merchants, including eBay stores, are also offering daily deals.
Now if you're wondering what to do with your old electronics, many stores like Target, Best Buy and Wal-Mart, along with online sites, have buy-back programs and they pay you with cash or store-branded gift cards.
