Let me say that although I hate shopping, I love Costco. These are the states that I have purchased something at in the previous 12 months.
Alcohol sales vary based on state and/or county/city law. Of course there is Canada, but that is the land of government controlled most things, but even that too is easing up a little bit. I will limit my discussion to those two counties as that is the limit to my Costco purchasing.
So its either Beer & Wine ONLY, Wine/Beer/Liquor, or Nothing.
NV - Everything
TX - Beer & wine ONLY
LA - Everything
SC - Everything
TN - Beer & wine ONLY
MI - Beer & wine ONLY
There is a bit of distinction over liquor. Many stores have an attached liquor store outside, but who is selling and what they sell varies from state to state. TX has an attached, but Costco does not run it, and they carry no Kirkland products. Too bad. SC has an attached liquor but it IS run by COSTCO, and it does have Kirkland products, which are really well priced. NV and LA sell Liquor right in the store. Kirkland sells some great Kirkland branded products at some really go prices.
Kirkland Branded products are some of the better priced deals for quality products.
A 1.75 L of Spiced Rum of $14.95, the upscale version of Vodka (suppose to compare with Grey Goose) was $20, also 1.75L.
Remember Costco is never about selection, it is about buying THE best or some of (in the case of wine or beer), and selling those a good price. Costco was never about unlimited choice. That is for sure.
