Hey, it's your money, so you're the boss. But I have to tell you that picking up stuff at Point Roberts is easier than picking stuff up from some of the courier. While you're down there, you can also get some cheap gas as well and save another $10 - $15 if you get a whole tank.
In the past, tax, duty, and brokerage charges were either paid to the courier when they deliver / I pick up the item. Or in the case of DHL, they mailed me a bill after I've picked up my parcel. But things could be different now as I haven't had stuff shipped directly from the US to my Canadian address in quite some time.
Hopefully, others with more recent experience could chime in.
