Asda has revealed a selection of tech products offered in its Black Friday deals, including Xbox One game bundles, Beats hadphones, an Android tablet, a Blu-ray player, and more.

Although the discounted products won't be available to buy in-store until Black Friday (28 November), the Walmart-owned supermarket has jumped the gun on many of its UK rivals, revealing a handful of products expected to receive major discounts during the two-day sale.

Products to go on sale 28 November, with prices revealed on 27 November:

  • Polaroid 40in TV - current price £249 - Black Friday price £139
  • Xbox 360 bundle with Halo 4 and Forza Horizon - current price £349 - Black Friday price £99
  • Beats Solo Monochromatic headphones - current price £169 - Black Friday price £79
  • Polaroid Tab 8 Android tablet - Black Friday price £79
  • Call of Duty Advanced Warfare on Xbox 360 and PS3 - Black Friday price £25

Products to go on sale 29 November, with prices revealed 28 November:

  • Polaroid 32in TV - current price £179.
  • Archos 70 7in tablet - current price not listed.
  • Xbox One bundle with Call of Duty and Sunset Overdrive - current price not listed.
  • Skylanders Trap Team Starter Pack (Xbox One) - current price £45.
  • Nerf Hailfire - current price £70.
  • LG BP135 Blu-ray player - current price not listed.

Asda stores nationwide will be opening at 8am on Black Friday (28 November) and the following Saturday, and shoppers are urged to plan ahead. Queues last year began at 5am and customers are only allowed to buy one of each discounted product. The supermarket has drafted in 2,000 extra staff, including security guards, and will be operating a special queuing system to cope with demand.

Extra security staff may well be needed, as last year a stampede at an Asda in Northern Ireland lead to one woman being taken to hospital with a suspected broken arm. At another store a man was tackled to the ground by security guards for trying to buy two 60in televisions, when only one per customer was permitted.

Black Friday 2014 is expected to be the UK's biggest ever online shopping day, with up to £200m tipped to be spent in 24 hours, doubling last year's total.
