Trust me shipping within the US is very, very reasonable if done correctly
If it's big use parcel post if its light use first class package
For instance, a bright contractor in Alaska discovered that it was cheaper to send each individual brick to Alaska via USPS then it was by a standard freight company
Needless to say, USPS no longer allows the shipping of construction materials
Moral of the story, so long as it's with trustworthy people, group buy/shipping all the way
