Toys
Black Friday is not the best time to buy toys for the holidays. You will see those toys discounted for less about two weeks before Christmas.

Game Consoles Without a Bundled Item

If you're looking to buy any of the major video game consoles this holiday, you're likely to get more bang for your buck by opting for one that comes with a few extras. These were frequently discounted 30 percent to 40 percent off their retail prices.

Brand Name HDTVs
Black Friday is an excellent time to invest in a new HDTV, as we predict a variety of size categories will hit their lowest price points. But don't expect the best deals to be tagged with name brands. Typically, the rock-bottom prices will mostly apply to third-tier manufacturers. Instead, brand name TVs tend to see their best price of the year in January and February

The Latest Digital Cameras
There's no shortage of digital camera deals around Black Friday, but keep in mind that the premium current-generation models are just a few months away from being replaced by a new line of 2013 options.

Christmas Decorations
Deals on Christmas items get better the closer we get to the holiday itself -- and of course are the best after the holiday.

Office Supplies
For several years running, office supply stores like Office Depot and OfficeMax have released Black Friday ads in the hopes of encouraging an uptick in business. Unfortunately, these deals are generally no better than those we see throughout the rest of the year.

Jewelry and Watches
We're flagging this accessories category "Do Not Buy" for the entire holiday season. The discounts on jewelry around the winter holidays are no better than those around Valentine's Day, when baubles are at their most in-demand.

Winter Apparel
If winter apparel is on your list, it's smarter to hold off until January, when those items are added to clearance sales that take much deeper base discounts.

Apple iPad mini
The long-awaited iPad mini will set you back at least $329, and if it follows the price pattern of its distant predecessor, the first generation iPad, it won't see a discount until several months from now. While there's an off-chance that an attention-seeking retailer could offer an iPad mini promotion (the latest full-size iPad is included in the Target Black Friday ad, after all), the bottom line is this: The iPad mini features essentially the same innards as the iPad 2, and we're predicting that the latter will fall to $299 this Black Friday. Therefore, the iPad 2 will offer more screen real estate at a lower price.

Microsoft Surface RT Tablet
Like Apple's tendency to offer minimal discounts on the iPad, Microsoft might only offer a marginal deal on the Surface this season. But if Surface sales are weak, the tablet may instead go the way of the BlackBerry PlayBook, wherein we'll see its price fall considerably by the spring.
