Black Friday 2012 is quickly approaching. Here are the best websites to visit for shopping alerts:

BFAds.net posts leaked ads from all major retailers and offers a user alerts mailing list as well. The detailed navigation bar allows Christmas shoppers to browse buying guides, contests, ad scans, and online deals. Black Friday 2012 fans can also create a shopping list via the website and search for gifts by category.

BlackFriday.com also offers shoppers all the latest ads and boasts a cash-back program for online purchases at many major retailers. The often updated website also lists ad scans which are soon to be released at the top of the home page.

BlackFriday.GottaDeal.com is also filled with leaked ad scans from a vast array of both brick-and-mortar and online retailers. Users can sign up for shopping alerts and make sure that a single doorbuster is not overlooked.

Black Friday by BradsDeals guides shoppers to find the best doorbusters, coupons, Black Friday, and Cyber Monday bargains. The website publishes all the leaked ads from major retailers and handpicked deals from the publisher. BradsDeals also offers an iPhone app to aid holiday shoppers while they are on the hunt at the local mall.

TheBlackFriday.com may be a bit less visually attractive than some of the other shopping websites, but the detailed item posts come complete with a link to the actual item for more details. The navigation bar also lists links to the most popular Black Friday ads for quick reference. An iPad mini giveaway contest was a nice added attraction for deal hunters who frequent the website.
