The Plugin changes the multiplier and toggles between the subtotal and subtotal after discount when the cart is refreshed. We use multiple coupons and offer a free item per every $100 but unfortunately the plugin uses the BEFORE discount total instead of the after discount total. I used the filter to change the multiplier to use the after discount subtotal but when you refresh it changes back to the subtotal. Click refresh again and it changes back. It’s very frustrating and I think I will just build my own plugin rather than pay any more money for this.
The plugin always uses the before discount subtotal, because with multiple auto coupons on the same cart the coupons can conflict with each other, i.e. if coupon A and B both apply, but B offers a discount that would rule A out, what to do?
