Adding price adjustments

Just started using Strip so there may me an option I haven’t learned yet. We currently have 4 different price points for our match. Club member, Non-club member, Club member second run and non-club member second run. I set up 3 price adjustments to cover all these options. Problem I noticed is someone can pick more then one option reduce their match fee to zero. Is there a way to only allow one choice?

At this time there is not.
As the MD you will have to oversee and remove cheaters.
If you set the reg so they have to be paid and approved before they can squad then you can review/approve each one before they can move forward.
