Amazon has announced the date when its Black Friday sales will start at it's earlier than usual. Where it traditionally kicks off its BF event a week before the day itself, it'll start eight days beforehand this year.

Both retailers are offering price protection through most of the holiday shopping season as well, so if you buy early and the same item drops to a lower price, you can retroactively get that better deal.

Amazon will officially launch Black Friday on 21 November and deals will run until 2 December, it has confirmed. It means Black Friday on Amazon will be a week earlier than the official date of 29 November for the second year in a row.
