Manipulative strategies designed to target shoppers while benefiting online businesses are becoming increasingly common. This exploratory study investigates how varying degrees of deceptive design in an online shopping interface influence online shoppers’ perceptions, decisionmaking, and overall satisfaction. As a major online shopping platform worldwide, Amazon’s mobile user interface is the reference for this case study. While Amazon is lauded for its convenience, it has been criticised for incorporating manipulative tactics that can steer users toward decisions misaligned with their original intentions. Although seasoned users might overlook these tactics due to their established trust and convenience, new digital shopping platforms may face different challenges if they simply follow arguable industry standards. In this study, the interaction with two high-fidelity redesigns of Amazon’s mobile user interface—one that suppressed and one that intensified deceptive elements—were compared against the original app. Based on the perception and feedback of users, we then propose four key recommendations aimed at guiding new designers in creating online shopping experiences that prioritise an ethical approach to design. These recommendations focus on transforming potentially deceptive elements into features that improve users’ satisfaction. By addressing the delicate balance between manipulation and convenience in industry practices, this study aims to assist designers in fostering a more ethical digital shopping environment.
