Labatts Blue? That is nostelgic name I haven't thought of in a long time.
Basically, the beer and wine stores buys their product from the BC Liquor Stores and sells them usually with their markup in convienent locations and convienent times.
But if you are buying only a six pack, it wouldn't really make a difference at all except the beer would be cold. It would cause condensation in your luggage if you pack cold beer
