Isn’t this more of a Canada issue than kbdfans. DHL almost always charges duty fees for oversea shipment to Canada.

That’s a cool looking knob

GMK Nightshade hasn’t shipped yet so you’ll be able to grab extras once they go live and after the group buy participant receive their order. So I wouldn’t worry too much. When the extras are sold out across all vendors then unfortunately their wont be any more stock. If that’s the case then you’ll have to search the aftermarket or hope the best for a second round by the designer and vendor.
