Retail sales of sporting goods grew by 5.2 percent in Sweden last year, according to HUI. As previously reported, they had risen by 14.6 percent in November, but then they fell by 2.9 percent in the important month of December. HUI believes that the cause for this turn of events was that Black Friday landed on the Swedish salary weekend in November. People took the opportunity to buy Christmas presents in November when there were promotions and discounts on most things. Combining November and December, there was an increase of over 3 percent in Sweden.
