I can't vouch for the wine. Some of the cheaper bottles are comparable or cheaper than competitors.
Beer is around market value. Cheaper than Randall's, sometimes cheaper than HEB, and sometimes a little higher than the "cash discount" price of Spec's Liquor (the city's largest liquor store chain).
On Thurday's during the early "happy hour", 64 oz. of fresh "craft" draft beer to go (in a refillable growler) can run as low at $6.
Well, I don’t know the stores you mention but at my WFs the prices are astronomical.
