Longer term:
1. We have to make all shipping methods respect free shipping setting in the product.
2. If At least one product in the cart has paid shipping, free shipping should NOT be shown.

Sorry for posting on an old thread, but I have this same problem.  Most of my products are free shipping.  One product is NOT.   The "future solution" that abantecart had posted is the key answer.  I'm just curious if it has been implemented since?  I'm running 1.0.9, and marking items as "Free Shipping" on the product level yield a "No shipping options" during checkout.

Forgive me if this has been addressed already.  Searching the forum didn't seem to reveal anyone else with this issue (atleast with the criteria I've used!)

AbanteCart has been a pleasure to install and setup so far.  We're now getting into the details of products and solidifying the shipping tools.  Currently, only the USPS extension is active.  It has our account info, and it shows shipping options during the checkout process.  The problem I'm having is, the shipping options do not seem to take the product dimensions into account.  The weight is showing up correctly (right above the shipping options).

The weight does seem to allow/deny certain shipping options, but dimension does not.

If I enter the product info as 200"x 200"x 200" at 2 oz, the option for First-Class Mail Stamped Letter is available. (Larger options are also available)

If I leave the dimensions the same, but increase the weight to 16 oz, First-Class Mail Stamped Letter disappears leaving only the larger options available.

I know the dimensions are unrealistic, they are for testing purposes only.  Is there a way to get only the appropriate packaging options to show, based on the products selected?

Someone suggested I look into some of the USPS API options...
