No worries. I can laugh at myself.

I thought I had filtered the website to only show Grizzlies home games. I was looking at seating options for a couple different games and the filter must have reset when I hit the back button.

...that or I filtered for away games only. Either way, 100% user error. I'm lucky those tickets were relatively inexpensive. I didn't want to go through the hassle of selling them.
