Hello Thoussuethoill31
Good day and welcome to the SBB Community.
The total number of Saver Day Passes available per day is limited; it is a first come, first served product, the cost is dynamically. The higher the demand (the more people purchase it), the higher its price. Therefore, you cannot expect the Saver Day Pass with Half Fare Card to be exactly at 50% of the pass without half fare card. When a lot of people purchase the pass with half fare card, the cost for it is increasing quickly while the cost for the full fare pass remains unchanged, because fewer people are interested in it.
If you want a point-to-point ticket or a day pass at a fixed price, no matter the time of purchase and the number of passes sold, you should not purchase saver offers but regular fare tickets such as the Day Pass for the Half Fare Travelcard. Compare its cost for half and full fare passes, you will see tze half fare pass is available at half of the cost of a full fare.

Make sure you are logged in with your account when purchasing the ticket and the Half Fare setting is reflected in your personal information.
