Yeah im gonna do the same as well when i order bilsteins. You know what, i wouldn't stress over the duties, 18 bucks. I would make sure you know what shipping carrier is bringing them over the boarder.

Brokerage fees are what's going to kill you. UPS is the worse, probably gonna pay like $40 for the shocks, Fedex and DHL are slightly cheaper. If the place/website that's selling them to you would ship by USPS that's the way to go.

USPS charges like $5 flat regardless of what it is, plus the duties/taxes..

Trust me, im an Ebay whore.
