Yup, in BC now. I keep a two month supply now in advance. Basically it can take anywhere up to 3 weeks for your package to arrive. If it gets returned around that time, you want to leave enough time for it to ship again.
One time I ordered 6 bottles at once and it got refused. So I had them send it out in two shipments of 3 bottles and they both got through - one right away, and the other 2 weeks later (opened by customs, but they let it through)
