We currently use AWOCoupon with Hikashop and Taxcloud (latest versions) and are having a problem with fixed amount coupons zeroing out tax.
For example:
Product total: $21.99
Coupon value: $30
Tax: $1.21
Total with Coupon: $1.21
I've tested changing the settings in the configuration and coupon itself. Nothing seems to change the total being $1.21
How do we make sure this order total is $0?
