Fans are listing tickets even higher, but it appears like those prices aren't rational. TiqIQ, a ticketing search marketplace, says that the average listing price of LSU-Alabama tickets dropped by 10.1 percent from $699.10 to $627.91 over the last 48 hours. Before the season, TiqIQ had the game being listed at an average price of $420.93, so the two teams being undefeated heading into the game was still worth a $200 boost per ticket in the listing price.

After taxes, the median household in Tuscaloosa, Ala., is approximately $31,000. Let's say that someone who doesn't have ticket and lives in Tuscaloosa buys two at $500 apiece. That's 3.2 percent of their net household income.

After taxes, the median income in Baton Rouge, La., is $28,213. Let's say someone travels to Tuscaloosa and buys two tickets at $500 apiece. That's 3.5 percent of their net household income.
