I belong to a club that has sold components for 6% over price. I called today about the 231 and the conversation left me unclear as to whether they are still doing the prices.
As it turns out, I think the 1 lb. quantity might not be competitive, but the 8 lb. is about $10 under Powder Valley.
I will need to check further into the calguns group buys as one of the members, Irvington Arms, is near here.
