I checked the feature list and still have questions on a few requirements.

1. Ability to restrict shipping to certain U.S. States - either through a module or hacking code.

2. Ability to integrate real-time with shipping carriers like FedX.

3. Ability to alter shipping costs (e.g. Free shipping).

4. Let shopper purchase items, one of which is a club membership and they get the cub discount at checkout. I doubt this is feasible.

5. Ability to let site visitor click on 'store' and the page displayed will show "All" products. It's a winery so there are only a couple dozen products.

THANK YOU !
