Alaska sells no alcohol in the grocery store, though there are usually liquor stores adjacent to the grocery (i.e. in the same building). THere are also liquor stores not associated with grocery stores. In Costco (and probably Sam's CLub, but I don't go there) the liquor is in a fenced off section of the store, and you have to check out there. I much prefer buying wine in the grocery store, but, well, it's not worth moving for!
