This year, Black Friday falls on November 24. But many of the big retailers have already started their sales.
So now is the time to act if you want to bag a bargain without braving the crowds - and make sure the item you are after is not sold out by November 24.
Here are 10 great deals to grab before Black Friday 2017.
1. Tkria butterfly print girl's coat
The price of this cute coat, available in sizes suitable for little girls from six months to four years old, has been slashed from £28.99 to just £7.999 on Amazon.
2. LG 65-inch 4K TV
This sleek LG 4K television is an impressive 65 inches and could be yours for £500 less than usual if you head to Currys PC World this week. It now costs £999, down from £1,499.
3. Mercedes SLS child's car
You can now pick up this Mercedes-Benz ride-on model car with functional steering and horn sounds for just £25 from Halfords. That's 50% off the original price of £50.
