Product images scale up (1 tub → 2 tubs → 3 tubs) creating visual momentum toward larger purchases while "Most Popular" on middle option anchors choice.
Orange Subscription Toggle
Toggle switch (not checkbox) makes subscription feel like an "upgrade" you're switching ON rather than a commitment you're checking off - subtle but powerful UX psychology.
Delivery Frequency
Toggle Frequency selector only appears AFTER enabling subscription - progressive disclosure reduces initial complexity and makes the subscription decision binary (yes/no) rather than multi-variable.
