Flat screen televisions

If you are in the market for a new flat screen television, check out Wal-Mart and Target on Black Friday weekend, Vincent advises. The big-box retailers will likely offer a 42-inch HDTV as a door-buster special (which means limited quantities) for $300. Last year, the retailers had a similar deal, featuring a 40-inch TV for the same price. If you want a slightly smaller version, Vincent said the 32-inch will likely be priced around $200.

Samsung and Motorola tablets

Amazon's Kindle Fire at $199 started a price war with everyone, making Samsung and Motorola no longer the alternatives to an iPad, Wilson said. As a result, he expects to see some steep discounts on these devices. "This will be the first Black Friday where tablets go mass market," he notes. Wilson said to keep an eye out for the 7-inch Samsung Galaxy priced under $300 and Motorola's XOOM around $350, both down from about $500. Shelton predicts that some of the lesser-known tablet brands could even drop prices below $100. "The HP tablet blew up at $99, which assures us tablets will be lucrative," Sheldon said.

Black Friday Deal Predictions

Black Friday ads haven't leaked yet, but we've talked to deal hunters to discover what items are likely to be heavily discounted this Thanksgiving weekend. "Black Friday and Cyber Monday are legitimately the best days to shop," said Brad Wilson, online shopping expert and professional bargain hunter, who runs the sites Bradsdeals.com and BlackFriday2011.com. In fact, Jon Vincent, who runs the deal site BlackFriday.info, said prices are typically always higher after Black Friday. "There are not many pre-Christmas door busters." One good piece of advice when shopping Black Friday weekend -- look for bundle deals, said Brent Shelton, of deal site FatWallet.com. "If you need a printer, wait for the laptop/printer bundles, it will save a lot of money." To prepare your gift-giving list, here's a look at some of the door-busters you may find if you put down the fork and get out there early the day after Thanksgiving.

Digital cameras

Demand for point-and-shoot digital cameras is essentially dead because of improved camera and video technology on the iPhone and other smartphones, Wilson said. This means there will be some great deals on premium cameras on Black Friday. Wilson expects to see Superzooms around $150 and Digital SLRs around $300. There were 350 different camera deals last year, Shelton said, and he expects to see even more than that for really high-quality cameras with 14 megapixels.

Amazon's Kindle Fire

The Kindle Fire is already competitively priced at $199, but the device could go even lower. The newest tablet may pop up as a coveted "Gold Box" deal on Amazon and could be priced as low as $100, Vincent predicts. But Gold Box deals aren't easy to come by, and only a lucky few will probably be able to snag the device at this ultra-low price.

Laptops: RadioShack

Radioshack is already featuring a $300 Toshiba laptop, which has been one of the most popular deals on FatWallet.com. As a result, Shelton is predicting some high-profile, 15-inch laptops will be available under $300 during Thanksgiving weekend.

Batteries: Which AAs rate an A?

AAs are still the most widely sold battery type, used in many toys, radios, flashlights, and remote controls, and in some digital cameras, though more of those are using tiny rechargeables. We tested nonrechargeable lithium, nickel oxhydroxide, and alkaline types. The longest-lasting was Energizer Advanced lithium. It took 809 photos before dying; the quickest to die, Walgreens Supercell alkaline, took just 133. Take manufacturer claims with a grain of salt. Duracell Ultra PowerPix, for example, lasted for 174 shots, which is indeed "up to 200 photos," as claimed—but any number under 200 meets that boast. Rechargeable batteries are a greener choice than any of the tested types. In past tests, precharged rechargeables from the major manufacturers provided about 300 shots out of the box and about 400 shots on their subsequent charge. If your town doesn't provide a way to recycle non-rechargeable batteries, it's OK to toss them in the trash. To find out where to recycle rechargeables, go to www.call2recycle.org. Bottom line Lithium batteries took more photos than the other types, so they don't need to be changed as often. The best performer, Energizer Advanced, costs $5.40 per pair but just 33 cents per 50 shots. The top alkaline battery, Duracell Ultra Advanced, costs $3.65 per pair but ends up costing 70 cents per 50 shots. Use lithiums in high-drain devices such as cameras and alkalines in low-drain devices such as remote controls. For toys that are used a lot, consider high-capacity rechargeables (2,350 milliamp-hours or more). Safety tips for nonrechargeables • Use identical batteries of the same chemistry, brand, and age. • Don't get batteries wet, expose them to fire, or pierce them; they could explode. • Don't carry or store loose batteries next to other metal objects. • Stop using a battery that feels hot, changes color, or emits an odor.
