A client has a site that offers free shipping over £20 as a delivery method. However, there are also some discount codes 15% off etc.
The client has a major issue with peoples baskets being £20+ then using a discount code and still qualifying for free delivery.
Is there a way of setting up the free delivery method to only apply to the basket after any coupons are used?
I also thought I could create a free delivery coupon and automatically apply it to the basket and set the priority after any other coupon, but can't seem to figure the rules out, other than giving a flat discount of the delivery cost on basket total.
