In Finland we have this thing called "black Friday", "black weekend", "black week", "black weeks", or, enhanced with double plural, "black weeksit", so loosely translated, "black weeksies". In any case, regardless of the name, this thing lasts a month or two and means that before it starts prices are increased by 30-40% to be reduced then by 20-30%, so that people pay more than normally for stuff they don't need. Nearly nobody is interested; but marketing departments keep pushing it and advertisements are overflowing.
