If you can find a ticket for under $800, snatch it now. Face value is $325.
Unless your ranking on the Ahearn Fund is pretty high (sub 4K, which is ~$4K in donations + season tickets over the past 3 years), I don't expect you can get tickets.
Last year Bama and LSU got 17K tickets each. Consider most people will be allowed 4+ tickets, that allotment will go fast...
Average price of tickets last year was $1600, but this includes all the lower level seats, suites/club seats. Upper level tickets will range from 600ish-A LOT. Set up a price alert on stub hub if you want to watch prices.
