Higher than that actually.  1k parts isn't even close to being considered enough volume to get any real discount.

Even if every single Bitcoin miner were to participate in this GB, the volume doesn't justify any real discount.  In the industry, you have to have part volumes > 10-100k (depending on many factors) to get any real leverage, and that applies only to customers who agree to long term business relationships as well.  Bitcoin is a drop in the bucket compared to commercial designs.
