My experience is the same -- about a week. It's prompt enough so I don't wonder "did they get my order?" but not lightning quick either. The business is located on an island and I think there are sometimes issues with getting stuff to the mainland if the weather doesn't cooperate.
I have always been pleased with the products and how powders are packaged in sturdy resealable bags and how everything is packaged nicely for shipment. If the shipping cost is less than what was estimated, they're good about issuing a refund. My overall impression -- this is a small business offering quality products and run by honest folks.
