I found that there are a lot of websites that are charging hugely inflated amounts for train tickets.
The advantage of using these sites is that you can book well in advance of the journey.
The official Swiss train company does not book tickets more than one month in advance. However, its prices are roughly 50-60 per cent of the price charged by other companies.
If you can wait for a month ahead of the data of travel to book, then use this: https://www.sbb.ch
