Duty-free liquor

[Watson42]

But, curlers drink? I had no idea.

It's what makes it bearable for the losing team, or what makes you the losing team in a "funspiel". My grandpa's got a broom with a sort of flask built into the handle. I should ask if I can have it when he stops curling.

I've found that ordering whiskey online from Scotland is cheaper than the duty free shops in US and Canada.

Actually this is not quite correct. You can shop duty free in the country you are LEAVING. The goods you purchase at the Duty Free shop are supposed to be consumed (or used if hardgoods) outside the country where you bought them.

Bob technically if you want a bottle while in Canada you should buy it as the US Duty Free and if you want to bring it home with you buy it in Canada. It's not really kosher to buy Duty Free booze in the US and then re-import it when you return home. I'm sure Wompet could clarify.

Dee hit the nail on the head. (Also, the Canadians are ... a little more observant, shall we say, about collecting duty on alcohol than the U.S. If Bob stopped at Duty Free going in, he paid the Canadians duty.)
And remember - you may be buying at a "Duty Free" store, but the actual duty exemption is 1L per adult every 28 days.
So if Bob is in a vehicle with 3 other adults, they can have 4L duty free, and technically should pay duty on any additional alcohol.

BTW - The answer is, it was cheaper to buy the booze going into Canada than coming out.
