We have a coupon-less discount for customers placing their first order. For various reasons these customers fail the checkout from time to time and we need to put their failed order through for them, in the admin.
We have a discount with coupon code that we can put in for them, however, there is the risk that this discount code gets widely known for some reason or other. Therefore we would like this particular coupon code to work for admin orders only.
Currently, I don't have any ideas or workarounds on how to make a coupon 'admin only'. Any ideas?
