I have this situation with a customer and a discount code.
We have a discount code to get a 15% off an order, but valid only for first orders. But then we have that customer who just keeps creating new accounts every time to get his 15% discount. How do I know it's the same? The address is the same and he just changes some letters in his name, goes with initials, etc.
So I want to block this discount, but only for this specific street address, to stop him from taking advantage of that discount code ever again.
Is there a way to do so in Shopify? Inside the discount code settings? With an app?
Thanks in advance!
