I know we're all about Costco here, but my bf and I stopped by the Smart and Final by our house today and discovered a wonderful land of bulk discounted products! Laundry & dish detergent, spices, condiments (though we don't use many), baking supplies, foil and other "rolls", booze, and half-gallons of Haagen Dazs ice cream attracted our attention. And unlike Costco, no membership fee.
However, my mom once stopped by one and had a bad experience (she said it looked grungy and smelled stale), so YMMV.
