When I create a promo code for Free Shipping in Expresso Store (version 1.6.0), it appears I need to set the discount amount to 0 and choose option 'Yes' for Free Shipping.
This works - but when the user is shown the value of discounts on the order it shows £0.00 - which causes some confusion. I can't figure out a way to get the order_discount tag to show 'Free Shipping'. I've tried various conditionals but no luck.
Can anyone offer a suggestion on this?
