It seems like there is no way to create a discount with multiple promotion codes. Is this true or have I missed something?
We need to generate thousands of promotion codes that each only can be used once. But it seems like the only way to do that with Episerver is to make a discount for each promotion code - as you can imagine this isn't ideal for our customer.
We have plan to make this in some custom hacky way, but perfect it will not be.
I wrote something while back about how you could this. Maybe it helps.
