Replying to How much taxes/duties to pay when buying from bc canada?

Hi, I don't know if this thread really fits in this board, and if not I apologize.
I was just wondering if anyone who live in BC canada has ever bought anything online from an the states.
I am thinking of buying a pair of boots but it's quite pricy in local shops compared to some american websites.

My only concern is the customs/duties that will most likely be charged when the item is shipped.
I was wondering if anyone had a previous experience with that?

And again sorry if I am writing in a wrong forum.
