Presale tickets are for time and location. They are sold to a degree already. The groups are not even made. The teams haven’t even qualified. The only ones that are, are US, Mexico an Canada. If you want one of those in presale, you had to buy for 4 - 8 games, high price locations. It is so stupid and greedy. You can’t not by terms resell them using any service. You could theoretically resell them directly person to person, but that is not easy.
