Nice point—no one loves hiding the savings. First step: make the discount a first‑class citizen in the data layer. Store it like a feature flag so you can flip it on or off per segment, test it in A/B, and track revenue impact. Next, wire it into the checkout UI before the user even sees the cart total. A small badge, a “You’re saving $10” line, maybe a little badge icon that feels like a secret find. Keep it unobtrusive but noticeable—too flashy and it looks gimmicky. Use progressive disclosure: show the full savings only once the user’s about to pay, so the reveal feels like a reward. Don’t forget to update the pricing line and taxes instantly so everything matches. Finally, iterate: gather click‑through and conversion data, tweak the wording, the color, the placement. That’s the recipe: data‑driven, visible, and a little bit of sparkle.
