During a seasonal sale, one fast-growing D2C clothing brand noticed something odd: even with clear markdowns displayed on product pages, users weren’t converting at expected rates. The discount was there—but somehow, it wasn’t grabbing enough attention at the right moment.

The team decided to test a simple but powerful idea: what if the value of the discount was embedded right into the CTA itself? Using CustomFit.ai’s JS snippet execution, they updated the button text dynamically—from a generic “Buy Now” to a more compelling:

“BUY NOW at $20 OFF”

This update didn’t require any theme file changes or dev effort—just a few lines of CustomFit.ai JS configured to trigger based on price availability and sale state. For users on Shopify, the integration made this even easier to roll out across multiple product templates.

To quantify the impact, the team ran a Price A/B Test using CustomFit.ai’s built-in testing engine. Half the visitors saw the original “Buy Now,” while the other half saw the updated, value-anchored version.

The outcome? A 25% lift in conversion rate during the sale period. Shoppers responded faster and more confidently when the offer was made explicit within the call-to-action. The urgency was baked right into the button—no extra scrolling, no second-guessing.

This approach works especially well for flash sales, limited-time offers, or holiday promotions, where clarity and speed drive action. With CustomFit.ai, marketers can modify pricing language on-the-fly, without touching code or relying on dev queues.
