Our campus bar used to have Lone Star for $0.65 apiece. They discontinued that and now I'm paying $0.80 for Shiner bock. Not bad (price or beer) and they open at 4pm. One of my grad students is bartending, so she'll give us a discount occasionally (we make it up in tips - I'm cheap, but c'mon...).
Nice to see people mention St. Arnolds (here in Houston) and Schell's. I did my undergraduate studies in a small southern MN town near New Ulm and we put away lots of the local Schells Deer Brand and other Schells specialties (come to think of it, we put away a lot of everything.... ah, college - that's why I never left). It's the oldest brewery in the US. They never shut down during prohibition because nobody had the guts to tell this town of German immigrants that they had to stop making/drinking their beloved bier!
When I'm feeling wealthy I buy the fancy imports and microbrews y'all are listing. My wife is particularly partial to Fat Tire Ale, out of Boulder CO. Cheers.
