I just buy them from Summit/Atech motorsports, by time you factor in the free shipping they pretty much end up about the same overall cost of anywhere out there.

Edelrock charges mega $ for their buy ins (I think it's $50K, at least it used to be) & do not allow just anyone to be a dealer for them (they dictate the # of dealers in a set State/area)& then they do not give a very good price break on their parts to their dealer network, hence why just about all Edelbrock heads/intakes etc are priced about same no matter where you buy them from.
