Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureDupeGuard stops customers from exploiting your discounts — it doesn't manage the discounts you create. Install it and it scans your recent orders for free, then shows a dollar figure: how much of your one-time discount went to the same shopper under a different email. It looks past the email address — Gmail aliases, disposable inboxes, repeat phone numbers — and links accounts that are one person.
OfferGuard identifies every buyer at checkout in under 50 milliseconds and enforces the rules you set, even when shoppers use guest checkout, a fresh email, a VPN, or a new shipping address. First-time customers receive the welcome offers you configure, including free shipping, free gifts, and BOGO, applied automatically with no discount code.
- Audit of your recent orders - see what discount abuse already cost you
- Links one shopper's accounts by email alias or repeat phone number
- Every flag explained in plain language with the evidence behind it
- Roommates stay safe - a shared address alone never links two accounts
- Identify repeat buyers across email, phone, address, IP, and device at guest
- Set per-product purchase limits and block or warn customers before the order com
- Automatically reject disposable emails from 3,000+ temporary providers
- Tag orders, flag risk, or hold fulfillment automatically when a rule matches
