Set an item to ship free in teh USA

After a couple searches I could not find the exact answer

I have a couple items I want to allow to ship for free in the USA only. I know how to setup a zone, but how can i link that item to the zone?

Have you tried just marking the Products as Always Free Shipping? This makes the Product free shipping to everyone ...

Then you can customize a few things to make Always Free Shipping only work for 1 Zone Definition ... if that can work for your site then this might be a good solution for you ...

What other shipping module(s) are you using?

Always Free Shipping is checked and i have a weight listed for the item.
For zone definition i have made a USAfree and have all zones in the USA selected.
I have free shipping and free shipping option enabled and both with zone USAfree selected
Also have the USPS module installed and have some international options checked.
When i pick an item that has free shipping and enter an address outside of the US it shows local pickup only

Okay, I have this written up for Zen Cart v151 on making 1 zone Always Free Shipping work and charge weight for any other zone with USPS:

see if that is able to get you setup correctly ...

Ok i'm not a big coder. I see they are working with the table module?

See if this one helps you and let me know if you need it adapted for the USPS October 30, 2014 K6 version:

I'm just going to drop the free shipping, its only 8 items, and they ship first class letter.
