Retail giant Amazon began its Black Friday sales early this year -- as in Tuesday, Nov. 1.

The online retailer kicked off the holiday gift-giving countdown by offering gift guides which feature suggestions on what to get for that person who has everything, and new deals posted every five minutes for items on its site.

Amazon has also created an alert system – "Watch-a-Deal" – to help customers keep track of bargains.

If you are a Prime member, you are eligible for additional deals, the company said. Prime members get a 20 percent discount on pre-order and new video games and two-day shipping. It costs $99 a year to become a prime member.

According to the National Retail Federation, the average American consumer will spend $935.58 during the holiday shopping season. More than half of that shopping, 56.5 percent, will be done online, the organization says.
