The January sales is a campaign period that lasts throughout January. It follows the Saint Stephen's Day sales as an extended sale with new offers and discounted products. You can often find better prices during the January sales compared to the Saint Stephen's Day sales.
The January is as well known as Black Friday and the Saint Stephen's Day sales, and just as many shops participate as during the other two big campaigns.
We have checked the price history from 1 November 2017 to 31 January 2018 on the 30 categories that were the most popular here on PriceSpy during Black Friday. Statistics show that the average lowest price on several of the categories is lower in January than it is in November and December.
The best chance to land a good deal on individual products is still on Black Friday, and around 25-26 December the chances are also really good in many categories.
