Quiz: "Tuesday" or "Friday"?

The correct answer is: Friday

Amazon is offering a week of discounts leading up to Black Friday.

Black Friday refers to the day after Thanksgiving in the US, which traditionally marks the beginning of the Christmas shopping season. Most retailers open very early and offer promotional sales, selling enough to put themselves "into the black ink".

Amazon is offering discounts on over 1,000 products from 21 November until Black Friday, which falls on 25 November this year. Shoppers will have to be quick, though, as only a limited quantity of a product will be offered at a discounted price for a short period of time.

Black Tuesday refers to October 29, 1929, one of the largest one-day falls in stock market history. Stocks lost 13 per cent of their value and more than 16 million shares were traded as a result of panic selling. The date is generally regarded as the beginning of the Great Depression in the US.
