If you don't use the pre-set filters, you will go through the Timeline and select the product with the price point in the respective period.
Now, the box with the product that can be selected opens. Alternatively, the most affordable product in the available period is also displayed. In the next step, add the product back to the shopping cart by selecting "Add to cart."
Once this is done, you can search for a new period and create a new reservation.
If there are restrictions on the product, this will be clearly indicated by the triangle symbol.
If a product is selected despite this, there will be another reference to the restrictions, and you must confirm to ignore these restrictions. Only then can the reservation process proceed.
