Shopify's "once per customer" limit only checks the email, so the same shopper can claim your first-order discount again with a new address or a Gmail alias. RepeatStop recognizes them by normalized email, phone and shipping address. At checkout it rejects the welcome code for buyers who have ordered before. Orders that slip through are tagged, explained and held for your review before anything ships. A 60-day audit shows how much welcome discount repeat buyers have already claimed.
