Canadian Shipping Fees/Taxes

Thanks guys. The guy I'm buying the part from seems like a stand-up guy. I spoke with him this morning and he mentioned if anything, I may have to pay a customs fee when the part is delivered to me. I've never bought anything from Canada though, so I wasn't sure how that worked.

He said just send him the USD amount through Paypal and it would do the conversion when it went to his account - easy enough. He's going to handle the shipping, which he's very familiar with. I just want to make sure the post office isn't going to hold the part hostage and make me pay a small ransom to pick it up. He said to help reduce any fees, he'd declare a lower value for the part. Does that help any?
