As a General Admission, Flexi 3/5, or Burrow Member, you do not need to pre-book tickets for matches. These types of Memberships provide you with unreserved seating allocations. This means that you can access the venue and choose your seat on a first-come, first-served basis within your allocated bay/s.
When attending a game, you can simply present your membership card or ticket at the venue entrance. You will be granted access to the general admission/burrow/flexi area, and you can select any available seat within that section.
It's important to note that while you don't need to pre-book tickets, it's still recommended to arrive early to secure a preferred seat, especially for popular matches where seating may fill up quickly.
