I'm planning a welcome bbq for all of my guests when we get to Hawaii. I'm from Canada, so I'm not sure if alcohol prices are a lot different in the states. I was planning on getting everything from Costco and was wondering if anyone has been there recently and remembers a general price of the alcohol ( beer, wine, hard liquor and anything else you might remember). Also, does anyone know if costco sells premade bottles of tropical drinks like blue hawaiians, mai tais, etc.. or if this is just wishful thinking. Thanks!
