Wow that Scottsdale price is awesome for online! Same amount would be $515 for me locally (at a dist. that is always in stock, but charges like $4 over spot per oz). The main dealer I like (who is not always stocked, just depends) only charges me $2-3 over spot/oz.
I'm definitely going to try Scottsdale for my next purchase, would be nice not having to drive anywhere - thanks for pricing that out!
