Have the seller contract with a freight forwarder on the Canadian side and have your amp customs cleared in the US and shipped to your door. The forwarder has contacts in the US, both for clearance and transportation. Sometimes it will be the same party who does both. Of course, you two will have to negotiate the price for all this. It ain't the cheapest route, but it is the easiest one for you.
Advice for shipping from Canada to US?
I'm in the process of purchasing a used amp from a seller in Sasketchewan, Canada, and having it shipped to me in California. It is a sub-$1000 USD purchase and not terribly fragile. What is the best shipping service to use for cross-border shipment? What should I know about the customs process?
Thanks in advance.
