Way too expensive man. Gridseeds are $160 USD ($175 CAD) at GAWMiners with free shipping to Canada. Bought a 10 pack of those barrel adapters for 10 USD ($12 CAD) shipped to my door in Canada from Amazon USA.
Your prices are out of line compared to your competitors. Especially since you need to tack on another 13% HST.
I seriously doubt that anyone would ship free to Canada.
Besides, you would pay customs and HST at the border via UPS or Fedex or PO...
Unless maybe they lie about the package contents.
Zeusminer wants $65 "shipping and handling" to ship $200 worth of product...
Then you will pay customs and HST and maybe broker fees at the border... YMMV.
It can only be free if the hardware is already warehoused in Canada.
