Help - need 0, 4, 8 awg Black Wirez Sig Series
 

Hey, I'm having trouble finding the following, all in Wirez Signature series black:
3' x 1/0awg
5' x 4 awg
15' x 8 awg

I'm in Southern Ontario. Trouble is every Wirez shop I have talked to so far only stocks the blue (power) sig series and uses it for (short) ground runs, rather than keep black in stock. Not to be fussy but I'm re-doing my install to improve cosmetics and I wish to use their black for ground.
I would be grateful for any recommendations for sourcing this?

TIA
