Re: The Macallan Fine And Rare Series
I do not know where you are from, but I know at least in the US basically any sort of Alcohol from an individual (i.e. someone without a license to sell alcohol) must either be given as a gift, the only legal way someone could sell it would be through a Auction house (in which case it is viewed as a collectible, not a consumable alcohol product). While no one is really policing the transactions between you and your friends, and they likely won't care if you sell to them.
It is a matter if you openly advertise that you are selling these products through say Want advertisements in local newspapers. All you need is the wrong person to find out about the sale, and you can get arrested for illegal sale of alcohol.
Though this is only US Law it may and likely is different in other countries.
