If you ship to a drop box in Buffalo, your shipping cost will be less than $230
and if you declare, like "some car parts" without mentionin cost unless asked,
at times you get off without paying.
Worst case scenario, you pay full amount.
With the custom laid off or furlough coming, there might be fewer custom officers
to check ..
I bought stuffs from ECS and shipped to drop box,I declared.. so far had not paid any hst or duty
