I've gone multiple times for a booze run and beer was $11.05 CAD savings per case (Busch) every time. A 1.75ml vodka or rye is just under $42 CAD, So a saving of almost $30 a bottle. That includes, purchase, exchange and duty. No tariffs on the products I purchase. But that's using Canadian cash at Ryden's Duty Free, not a card (debit or credit). Their exchange is better than a bank. Always pay with Canadian cash, it makes it cheaper.
