Yes and No. If you are running a contest that has an entry fee, we can set specific categories to be free. We've seen this option used when categories were based on age, and an organization wanted to offer free entry to a youth category, for example.
What we cannot do is set categories to be different fees. For example: one category a $10 entry fee and another a $5 entry fee.
It's either a set entry fee or free.
Overall, this option is not used very often with our platform, and so you would need to reach out to us and specifically request it.
