The rule of thumb for Black Friday electronics deals is making sure they are really saving you money. We’ve warned you before that some electronics deals aren’t as great as they look in Black Friday ads. So here’s what we found to be the best Black Friday 2012 deals in electronics that retailers have prepared.

If you’re planning to buy an iPad this Black Friday, then forget about getting a discount. However, Target will give you a $60 gift card at the purchase of an iPad 4, but you’re going to have to be at the store at 9 p.m. Remember the deal does not refer to the iPad mini. Target also features a great deal on Nook Simple Touch. It sells for just $49 but you will have to be there at 9 p.m. on Thursday.

Target also sells a Nikon L310 digital camera for $99,00 and a Memorex DVD Player at $19.99. Gamers will get a $20 gift card for the purchase of Halo 4 at the full retail price. You can also get the Xbox 360 4GB Kinect + Kinect Adventures and Kinect Disneyland Adventures for $200.

Another Black Friday iPad deal comes from Walmart. At a $399 iPad 2 purchase the retailer will give you a $75 gift card. The deal is available between 10 p.m. and 11 p.m. The Walmart Thanksgiving Day night deals also feature Emerson 32” 720p LCD TV for $148 and a LG Blu-ray player for $38.  Even if these sell out, the retailer promises a guarantee card for any of those items, but you will have to pay for it before midnight.

“That is nice because unfortunately most stores’ door busters in any store are limited quantities. Almost no one gives rain checks, almost nobody price matches on Black Friday” notes Edgar Dworsky, founder of Consumerworld.org.

Best Buy has a deal on the 13” MacBook Air that will help you save about $200 on that device. Apple’s 13” MacBook Air sells for $1,025 on Black Friday at Best Buy. The retailer also sells the Kindle Fire HD at $200 with a $30 gift card you can use in the store.
