When new regulations went into effect allowing grocery stores and other chain outlets to offer full-strength beer, wine and spirits, the Arvada Costco was ready to roll. It devotes an entire aisle to booze (next to the chips section, appropriately enough), with a prominent space reserved for its own Kirkland line of craft beers. But the cavernous warehouse also peddles plenty of additional brews, including many really good local beers. The major difference between this Costco and other liquor purveyors: The offerings here are often 30 to 50 percent less expensive than they'd be at the sort of retailers that once handled them exclusively. When it comes to cost, this Costco is Denver's new liquor price leader.
