TLDR
Circana research claims Best Buy's ads achieve 79% ROAS but that 16% of ad-driven sales go to rival retailers.
Circana reports that Best Buy ads generate a 79% return on ad spend relative to other media channels, measured against Best Buy's US sales alone—though the study provides no details on sample size, time period, or ad spend levels.
