Folgpris.no (followprice) – A way to track any price from any store (folgpris.no)

I had a problem. I had many pages with prices of products that I regularly checked to see if they had sales. This is not a good use of my time. So I made a price tracker that works with any page that is publicly available and tracks a price. Currently in Norwegian but Ill make a translation if there is interest.
