BUG found causing issues with shipping logic

Hello,

We have found a pretty frustrating bug in your plugin, frustrating because it doesn’t relate to what a normal side cart plugin should be interfering with. So took a while to troubleshoot and find the source. In your shipping availability code, you have used the fall back as being the default options. However, what happens is when a coupon is applied to an order reducing its % total, but the total remains above the free shipping threshold, its not matching your logic and defaulting to showing the non-applicable default rates HIDING the free shipping option.

So its great when the threshold is met without a coupon, but its a bit frustrating when you offer standard delivery and upgraded options as the upgraded options no longer appear additionally, again it’s a cart plugin not a shipping plugin remember. But as soon as a coupon is applied, free shipping gets hidden and the paid options shown, the total opposite to what you are desiring to achieve.

I believe it needs the logic fixing and I might suggest the fallback being native WooCommerce at least then if there are issues with logic it resorts to a native workable solution, currently it falls back to a broken and frustrating solution.

This is why we now always trial free version before paying for the premium version, as if I had paid $99 which is near double other side carts, and this was happening and affecting something unrelated to a side cart, I would not be happy at all.
