A: Hi Peter, BC is a special case due to the high cost of shipping from NJ.
The grout can be purchased locally in your area. Look for ANCHOR CEMENT or Anchoring Cement. You need about 1 lb. Per SP12 and 1/2 lb. Per SP10. No other type is acceptable.
If in doubt, email us a picture of the label on the material, or its exact name, SKU and manufacturer so we can check to see if this will do the job.
As far as the anchors, if the local west coast distributors (shown on our web site asphaltanchors.com) do not stock what you need, you can order from us directly through the online store (this one). Shipping via UPS Standard is relatively economical.
As far as volume discounts, indeed your order earns discount. The discount will show automatically when you enter the quantities.
Lastly, the issue of how many drill bits you need -- we recommend 1 bit per 100 holes, although if you go easy on the drill torque you can double the number of holes.
