They should have just said "we don't trust you to find a healthy alternative to something we make mad bank taxing".
My order finally cleared customs after sitting there over 3 weeks. It was a fair sized order, about 400ml of nic juice and some hardware, so I didn't think it would ever get through. But it did.
Of course, in the meantime I ordered more from Canadian suppliers, so now I have enough juice to last the wife and I more than a year.
It's not a bad position to be in.
