Meta AI Is Auto-Adding Unapproved Discounts to Your Facebook and Instagram Ads

On November 7, 2026, Meta confirmed that its AI-powered ad system is automatically detecting promotional offers from advertiser websites and injecting them into active Facebook and Instagram ads — even when those promotions have been turned off at the ad level.
The feature, called Offer Merchandising, scrapes your website for discount codes and promotional pricing and applies them to your ads without explicit approval. For ecommerce brands running tight margin offers or time-limited promotions, this creates a significant risk of expired or unintended discounts appearing in live campaigns.
How to Check and Disable It
- Go to Commerce Manager in Meta Business Suite
- Navigate to Settings > Offer Merchandising > Detected Offers
- Review any detected offers and toggle off any that should not be running
- To disable the feature entirely, turn off Automatically apply offers
Why This Matters for BFCM
Heading into Black Friday and Cyber Monday, this is a critical audit. If Meta has detected a 20% off code from a previous campaign or a landing page you forgot to update, it may be applying that discount to your ads right now — reducing margin on campaigns where you intended full-price selling.
Check your Detected Offers immediately. Any ecommerce brand running catalog ads or Advantage+ Shopping campaigns is exposed to this by default.
