Advanced shipping rate calculations

Hi everyone,

I’m currently having trouble getting my shipping to configure properly on wordpress with woocommerce. I’m using the advanced free shipping plugin and the USPS and UPS plugins to get live rates.

I ship all of my products separate, even if they are in the same cart together, so I need to calculate a shipping rate for every product in my cart. I was able to make this work, but certain products, that have a weight of 0, are supposed to get free shipping. The USPS live rate plugin isn’t able to follow the advanced free shipping rule and provide free shipping for this item, so it instead charges shipping on it of like $7.35.

I can’t figure out a workaround on this. Here is how I need it to work:

1. If weight = 0.0, Shipping is $0
2. If weight = >0, Shipping is calculated based on weight and product dimensions

And it needs to apply this logic to every product in the cart.

Does anyone have any ideas? Let me know if I need to provide more details. My store is currently in maintenance mode so you won’t be able to test it out live.

Thanks!
