We are using an app to limit the number of free samples we are offering on our store, but customers are doing multiple sessions to work around the limits we set. Is there a way to limit the number of sessions a household can do? We had someone use 4 different emails and 4 different sessions to order the free product 4 times to the same house. Is there a way to limit this other than manually canceling the order?
Or at least limiting the same customer (same unique identifier of email or phone number) from doing multiple sessions?
