Meta can add discounts it finds on an advertiser’s website to a duplicated Facebook or Instagram ad even when promotions were turned off on the original, according to a LinkedIn post by Bram Van der Hallen, a Meta ads specialist at Edge.be. Ads Manager’s duplicate dialog warns that eligible promotions can still show up on the copy, but the switch that decides it is a “Detected offers” checkbox in Commerce Manager’s Offer merchandising settings, which covers all of an advertiser’s ads. So a merchant running different promotions for different audiences could see the wrong discount land in a copied ad unless that box is unchecked. Meta hasn’t said whether the setting is on by default, and the screenshots come from a single account.
