DCBLeaked Discount Codes and Coupon Extensions: How Shopify Stores Fight Back
By Viktoriia Pavlova · · 6 min read
Quick answer
You can't stop codes leaking, but you can control where they apply. Use unique, limited codes, expire old ones, and use DCB to block every code on sale items or during your sale window.
Why codes leak
Influencer and affiliate codes are meant for one audience, but coupon sites and browser extensions collect and auto-apply them at checkout. Shoppers who were going to buy anyway get a discount they didn't need.
Damage control checklist
- Use unique, single-use codes for email campaigns
- Set usage limits and end dates on influencer codes
- Audit and expire old codes quarterly
- Never let codes stack on clearance
Make leaks harmless during sales
The highest-cost moment for leaked codes is your biggest sale, when they stack on already-reduced prices. DCB's scheduled blocking switches all codes off for your sale window, while allowing chosen codes you still want to honor.
