Around here I can find Bell's Two-Hearted Ale on sale for $7.99, Sweetwater IPA on sale for $6.99, and Sierra Nevada Celebration Ale (last year) for $8.49.
Trader Joe's has some good beer at great prices. Specifically Mission Street Pale Ale, Joseph Brau Vienna Lager and Trader Joe's Vintage Ale. Made by Firestone Walker, Gordon Biersch and Unibroue respectively.
In Minnesota there is a brewery called Summit that we can buy 12 packs for 13.00, their beers would stand up to the Sierra Nevada's, lagunitas of the world. They really only distribute in MN and are at brewing capacity, so unfortunately many here will never taste them.
Total Wines and More is great for selection and prices! Also Trader Joes does have great deals! Can pick up a 750 of Chimay Red often for around 7.99. I've even seen it for 6.99 on sale!
