How to block discount extensions such as Honey?

Topic summary

Store owners are seeking ways to prevent browser extensions like Honey from automatically applying discount codes at checkout, particularly VIP or exclusive codes not meant for public use. This issue disrupts referral programs and reduces profit margins.

Attempted Solutions:

  • One merchant successfully got Honey to de-list their site by flooding the extension with provocative coupon codes like “HONEY-STEALS-YOUR-DATA”
  • Several developers offered custom JavaScript solutions to block these extensions

Available Tools:
Multiple commercial services emerged offering blocking capabilities:

  • blockcouponextensions.com (by Clean.io)
  • Veeper app (starting at $59/month) - claims to be “the only app that still works”
  • Custom scripts from independent developers

Pricing Concerns:
Some merchants expressed frustration with costs, noting solutions around $300/month as prohibitively expensive.

Current Status:
The discussion remains ongoing with no clear consensus on the most effective or cost-efficient solution. Merchants continue seeking alternatives to protect exclusive discount codes from being scraped and publicly shared.
