In the United States, Black Friday is the Friday after Thanksgiving. Since Thanksgiving always falls on the fourth Thursday in November, the following Black Friday is considered the start of a traditional family weekend and the beginning of the Christmas shopping season - with huge discounts.
Now Apple has announced a four-day shopping event via newsletter, among other things. This begins on Friday, November 23rd, 2018 and ends on Monday, November 26th, 2018. It is still unclear which products Apple will specifically offer. It could be an immediate discount on selected products or a gift when purchasing certain products. iTunes, App Store or Apple Store credit cards and headphones could be considered as gifts. As soon as further details are known, we will inform you.
