Alpha 8 is mostly working with my fresh install. Two things:

1. Someone already mentioned this, but the option for Delivery pane to not be shown if products are not shippable is not working. I poked around in the code via bazaar and from what I can see the only place that the uc_cart_delivery_not_shippable variable is evaluated is in the billing pane. There are no checks for the Delivery pane for whether the cart is shippable. However, I'm not sure what the patch should be... I did confirm that the shippable variable is set to 0 in the uc_products table for the item in question.
2. The "Add to cart redirect" is not working. It always goes back to the product page. I'm not sure what the problem is here since I confirmed that the add_to_cart() function is returning the correct redirect value. Anyone else have this problem?
3. Kind of minor, but worth a mention. The line item taxes calculation isn't being updated if I change the Delivery Zone more than once. What triggers line items to be recalculated?
