Thrifty Beer

Stock your hotel-room fridge with help from LA-based Thrifty, which Gmaps a particular area of town's 10 cheapest retail outlets, breaking things down by brand, quantity, and price per ounce, i.e., Fat Tire 12-packs at .09 cents/oz vs 30-racks of Natty Light's .03/oz (why choose quality over quantity when you can have both?).
