What we found when we measured prices
In the summer of 2026, Sparebørsen tracked 7.8 million price readings across 1.2 million products at more than 350 Norwegian online shops. The aim was to see how often prices actually change, and in which direction.
Prices fell 2.4 times as often as they rose: 36 per cent of the products got a lower price, 15 per cent got a higher price, while 49 per cent stayed unchanged over the period we measured.
Some products move more than others
One in seven products fell 10 per cent or more in price over the course of seven weeks. That is not small change on a more expensive item.
We saw the most price movement in home and garden, and in sport. There, prices change regularly, both up and down. The most stable was health and beauty, where prices largely sit still over time.
The full report, with more figures and detail by category, is openly available at spareborsen.no/prisrapport.
So when should you actually shop?
The honest answer is that there is no fixed date or weekday that guarantees the lowest price. What the figures show is something else: that prices in Norwegian online shops move far more than most people think, especially in categories such as home and garden and sport.
If you have the time to wait and keep half an eye on things, particularly on a product from a category with a lot of movement, the chance that the price falls within a few weeks is greater than you would expect. If you need the item now, there is no reason to put off the purchase in the hope of a drop that may never come.
Cashback works whatever the timing
This is where cashback differs from chasing the right moment. Whenever you shop, whether the price has just fallen or has not moved for weeks, you get a share of the purchase amount back as long as you click through via Sparebørsen first.
It does not make the job of watching prices redundant, but it is one move that gives something back quite independently of whether you hit the right week or not.
