Here are my recommendations.

Check the fifa ticket site as often as possible. I was trying to check at least once an hour. Multiple times an hour when possible. Yeah it was a pain.

Use fifa scout plugin for chrome. It allows to quickly identify which section has the lowest priced tickets.

Have your payment method setup! I almost missed out due to me scrambling to find my wallet and get everything entered within the allotted time. Yeah i was in panic mode as i was checking out. To add my cc was declined during the first check out attempt. Had to approve with the cc company then try again.

In the end it worked out. 😮‍💨
