Hello,
In order to reduce the risk of your discount codes being exploited in the wrong way, you can always ask for customer ID or address verification, especially, for large orders. I invite you to try our app that we’ve recently launched https://apps.shopify.com/fraud-judge
On top of the 3months free trial we now have lifetime discounts available to the subscription plans. In return - if you like our service, we would appreciate it if you left a review on the App Store.
Here’s your 25% lifetime discount code: XKAGS7
Best Regards,
Martins
