I think the Bastard rep closest to you is Amos unless there're others in BC or Sask. You can PM him and see if he has any left. I think I rmb reading somewhere that he was low on the BBB's too.
No idea how often they restock. You should ask them directly via the contact button on the upper right corner of the ASCMart page.
If not, you can try Metal Techs as well. I think I've heard some good things about them although I've never tried them personally. They can be found here: click
