Price fluctuations are quite normal at Digitec and elsewhere. The price history is visible in the product itself, so no one is fooled. If you compare carefully, you won't have any problems. Before buying, I always search Google, Toppreise and other platforms for the current best prices, then you know where it's worth buying and can decide for yourself whether you want to pay more to buy the product from a certain retailer. I hope I have helped you.
