Well, nobody likes to give money away. The advantages of living in socal is that you can get things for retail prices the next day. It would probably take longer or be more effort to go through a middle man like an LFS when you can order directly online for the same price.
I will sometimes order small items that would encrue a shipping charge at my LFS, but that is not nearly enough of a sale to make very much profit from.
And now that BRS is offering free shipping on all their items, it encourages people to order small items through them that would require shipping costs from other retailers.
And don't even get me started on amazon...
