I tried really hard, but here is what i was eluding to the other day.

'Note that if you, the vendor, do not charge and collect RST, the responsibility falls onto the purchaser:
“If taxable goods and services are purchased for own use from an out-of-province vendor or supplier who does not charge and collect RST, the purchaser is required to report and pay the applicable RST on the total fair value”
Don't get me wrong here, i had suspected, but wasn't sure about this myself.So, you SHOULD be paying your local sales tax on anything purchased, no mater where it comes from. Whether you want to be part of the problem or part of the solution, is your bussiness.
And thats just my opinion of course.
