Do you like booze? Vodka? Scotch? Rye? Rum? Wine?
I absolutely love caesars and I refuse to use any vodka in them but Kirkland brand. Why? $50 for a 60oz and it's better than Grey Goose. I'm not kidding about that either. Their secret is that they actually bought a Grey Goose distillery in France. You get all of the quality and don't get ripped off on the price.
Next is their rum. Slightly cheaper than other places though not worth a long trip. Go for the scotch. Usually $20 or more cheaper than the average liquor store though not a huge selection.
It's a sweet stop for your giant bottle of vodka. Step next door into Costco for your giant bottle of tabasco & worcestershire, 4 pack of Clamato, bundle of celery & massive container of celery salt and you're good to go.
