So I'm running into a problem where some of our customers are being charged for shipping... and some of them are not. We have free shipping set up for orders over $60, but these orders getting free shipping are not even close to $60.

We are using Zone & Weight shipping, and although I think it is set up properlly... this may be where my problem lies. Also, when I go to checkout it gives me two different shipping options/prices to choose from, even though I only have 1 custom ship method which I'm using.

Any help would be greatly appreciated. Or any advice on an easier solution. I don't want to do UPS shipping calculator, because in many cases it costs our customers much more to ship through UPS.

Okay - I figured out what the issue was. I had set up a 15% discount coupon for new customers to the store. However, the shipping amount at the bottom of the coupon was set to 0.

I feel that although I was able to figure this out, it wasn't very clear that you need to put -1 if you don't want to override shipping amounts. It would be helpful if this was highlighted or made more clear.

I think it would be more clear if it charged normal shipping by default, and then gave you the option to offer free shipping on the coupon with a checkbox.

If that is not possible, then I would just make the help text bold or red, so that it is not overlooked so easily.
