*update
We have been busy updating our website to make sure all information such as price information is even more accurate than before. We have decided to not show categories that only hold products that our out of stock. As soon as those products are back in stock the categories will be visible again. This should clean up the website and eliminates the possibility to land on a empty category page.
Furthermore product prices on category level were sometimes not correctly displayed and were different from the product page prices. This is now also fixed.
