Welcome to SeatGeek! In order to maintain our marketplace we do have fees, but we'll always show you a thorough price breakdown of your order before you can checkout. Plus, we've got options so you can actually search for tickets and see the fees included in the price from the get-go. Simply use the filter "Prices with fees" when searching for listings.
You can read more about that here: https://support.seatgeek.com/hc/en-us/articles/360036685293
I hope that helps! Please let me know if you have any other questions--
SeatGeek CX Team
