2" hot dipped galvanized ring shank nails

Not sure I'm suppose to be posting a question like this but here it goes.

I live in the Peace River area and i've searched high and low to find a supplier of (hdg) 2" ring shank hand drive nails. Local suppliers said they can't help me (3 different ones) and found lots distributors online but the shipping costs more than the nails do. I'm installing cedar shingles for a customer and he wants me to use the ring shank nails and to hand nail the shingles, I found some stainless steel nails but there alittle costly.

So if anybody knows where to get these nails either Edmonton or Calgary would be so much appreciated.

Thank You in Advance
