Sainsbury's Black Friday deals 2015

Sainsbury's throws open its doors to Black Friday bargain-hunters at 6.00am and will stay open until 10.00; deals end at midnight on Sunday.

It's only the second time the company has taken part in Black Friday, and it's taking a fairly low-key approach. Deals look set to be in-store only.

Products on offer include the cult Nutribullet smoothie maker for £65, down from its usual £85. Even cheaper is the Morphy Richards Easy Blend and Juice, down from £40 to £25.

Meanwhile, for those who prefer their drinks a little less healthy, there's the Krups Mini Me coffee machine for just £45, less than half its usual £100 price.

Other kitchen gadgets on offer include the Breville Sandwich Press, which was £30 and is now £20, while the price of the George Foreman Family Grill has gone from £50 down to £20.

The Celcus 32-inch HD Ready LED TV with Freeview has been reduced from £180 to £100. Meanwhile, the Blaupunkt 40-inch full HD LED TV with Freeview HD has dropped from £280 to £160, and the NOW TV Box v2 is down from £25 to £15.

For those planning to take plenty of photos this Christmas, Sainsbury's is also highlighting the KitVision HD10 12-megapixel camera - down from £150 to just £70. Meanwhile, the White Polaroid 40x optical zoom bridge camera at £75, half the usual price. A set of Sony ZX-610 Headphones is now down from £50 to £20.
