NookLoganMafia, go into the presale and click the link for ADA-accessible seating. You ought to be able to find tickets in the lower price ranges via that method.
Thanks. Persistence actually paid off. I just kept clicking for two tickets in Tier 2 and after about 10 times of it telling me that there weren't tickets in my price range (and offering me floor seats) or telling me there were no tickets available, I landed two tickets in Section 210, Row A. AMAZING SEATS. Not sure if it was a Tickets.com glitch or what, but I grabbed them. I know my mom will be super psyched and I know that she and my dad will love the show. It's a bucket list show for both of them.
Thanks to everyone for your help and insight. Much appreciated. I love this community already for Nats discussion -- this is just the cherry on top.
Oh, and one last thing -- $25/ticket for "convenience fee"?!?! The Lerners are taking in a hell of a rake.
