The biggest discounts of the year follow a predictable rhythm. This calendar shows when the most important sale events take place, what to expect and which shops usually join in.
Exact dates are set by the retailers (and for official sales in some countries by law) and can shift from year to year.

Digital game stores run large seasonal sales in summer and over the holidays – Steam's Summer and Winter Sales are the best known – with discounts on thousands of games.
Amazon's multi-day deal event for Prime members, with discounts across almost all categories. Other retailers often run competing promotions at the same time.
Laptops, tablets, headphones and school supplies are promoted before the new school and university year. Some brands offer special prices for students.
The Friday after US Thanksgiving and the following Monday – many shops stretch it into a whole "Black Week". Not every Black Friday price is a real deal, so it pays to know the normal price beforehand.
