I assume that you went to Aura. I've found that Global (101 & Zanker) and Jackel (Watsonville) have better prices than Aura. Forget southern.
I've gotten QS 4/4 walnut for less than that at jackel.
Since the walnut and maple need to be trucked in from the eastern half of the country, they are naturally going to be more expensive out on the west coast. On the other hand, PO cedar, Alder, Claro walnut, sweetgum, sycamore and other native trees can be found more cheaply if one looks around.
Then again, I can work with the garage door open year around, have RH usually well under 50% and 330 days of sunshine a year, no air conditioning required.
