IIRC, visitors aren't in Z anymore. I think the only lower level visitor seats are in A and B. And even if I'm wrong, no way does Buffalo bring enough fans to fill their allotment that far over.
I know you probably want the security of having tickets in hand, but you'll save some money if you wait until gameday and buy on the street. I'd say tickets for that one will be going for 10 bucks or less by kickoff.
Okay, good to know. I know that getting them on the street would probably be better, but I really, really don't like to haggle or anything like that. What to do?
