Welcome discounts and first-time-customer codes get abused by repeat buyers creating new accounts. They use email aliases, slightly reformatted shipping addresses, switch browsers, or go incognito. Each reuse costs you the margin you priced into new-customer acquisition. OverlayIQ detects these patterns and rejects abuse at checkout before payment is captured. The buyer sees a clear message. You keep your margin. No chargebacks.

• Link guest checkouts and multiple accounts to a single master identity.
