We are migrating from a Magento site where we have offered coupon codes combining a %OFF plus Free Shipping and/or BOGO %Off plus Free Shipping for the past 6 years! If I had known we would not be able to implement such a common promotional combination, we might not have elected to make the switch to Shopify.
I really can’t believe this isn’t a standard option or that none of the app developers I’ve looked at have truly addressed this either- at least not in a manner that is easily implemented and maintained.
