'Black Friday' is the traditional US discount shopping day which falls on the day after Thanksgiving in America – this year, that's November 25th. Huge discounts are offered to US shoppers, and the practice has now spread to the UK.
Last year Amazon offered five days of limited deals on 500 products, and this year the online retailer is promising price cuts on twice as many products, including books, music and electronics.
Today's offerings include discounts on a range of TVs: Panasonic TX-L32E3B Viera, Toshiba VL578B, Samsung PS50C7000 plasma, Toshiba 19DV501B with built-in DVD player and Panasonic TX-L32C4B. Prices to be confirmed.
Elsewhere in the electronics sale you'll find a Pure Contour iPod dock/DAB radio, a Samsung SMT-7800 500GB Freesat HD TV recorder, a Sony BDV-EF200 3D Blu-ray 2.1 home cinema system, a Sony BDP-S570 Blu-ray player and a Logitech Harmony 900 universal remote control. Oh, and a pair of Creative WP-300 wireless headphones for £59.38.
As for DVD box sets, there's the Scarface Limited Edition and Star Trek: Original Series and Star Trek: Next Generation collections on offer.
Other Deals of the Week we've spotted this morning include Pure's Evoke Flow DAB/internet radio for £99.99, a Gear4 HouseParty 5 iPod dock for £35.99, headphones from £9.90, Creative D80 wireless Bluetooth speakers at £30.49 and Creative Inspire S2 wireless speakers for £84.99.
But remember, stocks are limited and the Black Friday 'lightning deals' change rapidly and are only offered for a short period of time. So you'll have to be quick if you want to grab one.
