Response has been very complimentary and positive and I am always happy to hear such comments.
I have an order of supplies arriving today and will soon have 8 calls finished (I finished the call bodies and am waiting on the materials to fit/tune the reeds which should be done by the weekend). I also have more material in the order to make about a dozen more calls, but it will be a few weeks before any of those are ready to offer for sale.
I checked the USPS website this morning to see what it was going to cost to ship a call to Canada.
I was SHOCKED to say the least!

Today's prices are (in US dollars) $26.85 for priority (insured) and $17.25 for first class (uninsured, and the buyer would have to take the risk of it being damaged or lost).
I could ship up to 3 calls for that price, but then the recipient would be looking at a total value subject to duties/fees if I'm reading correctly.
It looks like those members living north of the border are not going to be buying any of my calls again this year unless someone can suggest a way to get them shipped more economically, or you have access to a PO box in the US.
