Black Friday's considered to be the start of the American Christmas shopping season, and has spread to the United Kingdom since going fully international in 2014. British online retailers have taken to it with enthusiasm, and UK gamers are eager to pick up bargains as their American cousins.

According to the National Retail Foundation, the four-day Thanksgiving weekend brought $50.9 billion. Black Friday 2014 gave Walmart its second best online results of all time, with Walmart.com serving over 500 million page impressions. Physical traffic to Walmart stores more than doubled on Black Friday from 2013 to 2014.

Consoles are hotly desired on Black Friday as they make up Christmas presents for numerous people. Xbox One emerged the winner from Black Friday in 2014, accounting for 53 percent of all consoles sold during the sales. PlayStation 4 had also enjoyed a long string of monthly retail wins leading up to Black Friday last year.

Amazon has some of the better deals on the market, both in the US and the UK, during the holiday shopping extravaganza. However, many of the best deals are only available for a set amount of time.

You can expect plenty of game, console and accessory sales, and probably even a few deals on video cards and other PC parts.
