About the RepeatStop: Discount Abuse
RepeatStop stops repeat buyers from claiming your first-order discount multiple times. Shopify's "once per customer" limit only checks email addresses, so shoppers can easily reuse welcome codes with a new email or Gmail alias. This app recognizes the same customer by normalized email, phone number, and shipping address.
At checkout, RepeatStop automatically rejects welcome codes for buyers who have ordered before. It sees through Gmail dots and aliases, different phone formats, and address spelling variations. Suspicious orders that slip through are tagged and held for review before shipping, with clear explanations for every flag.
The 60-day audit shows exactly how much welcome discount repeat buyers have already claimed from your store. You can blocklist problem customers and exempt wholesale, staff, or B2B tagged accounts. Stop paying your first-order discount twice and protect your margins from discount abuse.
