I don't use warehousing. It almost seems like it caches my account. I logged-off then back in, and the shipping started working (mostly). It still shows "free shipping!" in the cart in the upper-right, but when I go to the cart I finally have USPS options. Is there a server cache setting I'm missing? And, it still doesn't add the handling fee. I've added this fee in the carrier, in the settings, etc -- but it never seems to add it.
