Free Shipping when $0.00

I am receiving coupons from halfoffdepot.com for items that have already been purchased on their site. Once a customer puts in the coupon its should reduce the total price of the unit to $0.00 which it is however it is still adding shipping cost.

So here is what I tried so far:

I added a new shipping method named Free Shipping I set the min at $0.00 and the max at $0.00 thinking that this option would only show up if the final total was $0.00. It shows up regardless, probably because I'm doing something wrong.

I also don't want the other shipping methods to show up at all when the final total is $0.00

Now I am sure there has to be an easier way to add free shipping. What am I not seeing?

If you want to add free shipping when the order is free, you should put in the max price of your free shipping method a price of 0.01 because 0.00 is considered as if you didn't put anything in the option.
And for the other shipping methods, you should set a minimum price of 0.01 too.

Thanks Nicolas I tried leaving the minimum at 0 and the max at .01 but now the free ship doesn't show up at all. I also tried adding a .01 to all of the other ship methods for a minimum but that didn't work either. It seems that the min and max only look at the total price and not the final total or a subtotal (subtotal doesn't exist). Since the Total price of my item is $19.99 the free ship won't display unless I make the min or max 19.99

No I think that it comes from something else. Please make sure that the "Include virtual products price" option of your shipping methods is turned on and try again.

Here are all my shipping methods



Here is the free ship options



Here is what happens when I put the code on my site



I tried turning off and on again the option but free shipping still doesn't appear unless I change the max or min to 19.99

Ah yes, it's the price without the coupon which is taken into account for shipping methods price restrictions.
That's normal.
You would have to change the line:
$price = $order->total->prices[0]->price_value_with_tax;

to:
$price = $order->full_total->prices[0]->price_value_with_tax;

in the file plugins/hikashopshipping/manual.php if you want it to use the price with the coupon included.

Ok Nicolas I normally don't write in all Caps but sometimes you just have to let everyone know.

I LOVE USING HIKASHOP AWESOME AWESOME AWESOME SUPPORT!!!!

Ok I got that out of my system and I guess by that you already know that what your wrote above is working thanks again and HAPPY NEW YEAR!
