Cyber Monday offers a great opportunity to shoppers who are weary of stores, lines, crowds, and the cold. Since its moniker was coined by the National Retail Federation in 2005, Cyber Monday has built giant followings among retailers and their customers alike.

Black Friday provides consumers deals on clothes, electronics, toys, and other gifts, but Cyber Monday does the same -- except all the shopping can be done in the comfort of home or office.

Retailers detail their special deals for Cyber Monday and Cyber Week on their Web sites. You can also check out some aggregator sites for coupons and lists of discounts from a range of companies. Some of our favorite aggregators include SlickDeals, FatWallet, Dealery, and DealNews. SlickDeals has a special Editor's Picks site where they find the cheapest prices for some of the season's hottest gifts, which is particularly useful.

RetailMeNot is also a great place to check for a list of coupons from stores such as J.C. Penney, Kohl's, Lands' End, Macy's, and others. If you're still looking for original deals, you can find some by checking Twitter and keeping track of #cybermonday and #deals.

Below is a list of some of the hottest Cyber Monday deals announced by Amazon.com, Walmart.com, Target.com, and ToysRUs.com.
