I am sorry, but I don't completely understand what you are asking. From what you write I assume you have purchased the 4-day Swiss Travel Pass Flex Combi. Please note that you can buy tickets at half the fare between the first and last free travel day, as explained here. So you can't use all free travel days and then buy discounted tickets. But you can use one free travel day to travel to Champex, then buy discounted tickets to Zermatt, and use the remaining 3 free travel days later.
Tickets at both full fare and half fare are always available. They do not sell out. You can buy them at any train station. If you use a free travel day, you do not need tickets.
Please let me know if this answers your question or if there's anything else you need to know.
