Why IN THE WORLD don't they sell this here?

I went to visit my country - czech republic - and had some french fries with their tartar sauce - it was delicious!!!! I hate the tartar sauce they sell in canada, but the tartar sauce in czech republic was sweet and VERY good I'm not even kidding. How come they don't sell it in canada and america, when it tastes so good? Why do they have to sell the blah tasting tartar sauce?
