Shifting Demand with Transparency
Balancing Profitability and Trust by Redesigning Same-Day Delivery Fees
Impact Snapshot:
65% Reduction in peak-hour fulfillment pressure
$517k+ Incremental Revenue generated within the first quarter of stabilization
38% Behavioral Shift in member selection toward lower-cost fulfillment windows
Executive Buy-In: Research insights were so definitive they led the CDO to mandate the UX-recommended design, bypassing a proposed A/B test.
Situation
BJ's Same-Day Delivery (SDD) was a victim of its own success. A flat $14.99 fee for all time slots led to 60% of members defaulting to the earliest "under 2-hour" window. This created massive fulfillment logjams, forcing the company to route overflow orders to third-party providers at an additional cost of ~$2 per order. We needed a strategic lever to rebalance demand without damaging conversion.
Task
My team's mandate was to design a "Priority Fee" for the <2-hour delivery window. The goal was to generate incremental revenue while incentivizing members to self-select into later, more efficient fulfillment windows.
Action
Research as a catalyst for executive decisioning:
The Transparency Proposal: Based on competitive benchmarking and accessibility standards, my team proposed a "Transparent Pricing" model (Design B). This featured the total cost listed explicitly next to every available time slot, ensuring members had full context before making a selection.
Stakeholder Resistance: Business stakeholders expressed strong concern that highlighting fees so early would trigger price sensitivity and lead to cart abandonment. They advocated for an "opaque" model where the total price was only fully visible in the final order summary.
Proving the Value of Trust: I led a rapid qualitative study to compare both approaches. The results were definitive: 100% of participants in the transparent group understood the pricing, with one member noting, "There's no surprises…I would have no issues paying those." Conversely, the opaque group expressed confusion and felt the fees were "hidden."
The Executive Pivot: While stakeholders were initially hesitant—agreeing to the design but insisting on a post-launch A/B test to "confirm" the data—our discovery work reached the Chief Digital Officer (CDO). After reviewing the research and both design variations, the CDO mandated we launch the transparent version and forego the A/B test entirely.
Results
The launch achieved its primary business objectives immediately. Within just four weeks, under 2-hour deliveries dropped from 60% to 22%, successfully rebalancing the fulfillment load. Furthermore, the Priority Fee generated $517,417 in incremental revenue in just 11 weeks.
Most importantly, the project established a new precedent: Transparency is not a conversion killer—it is a trust builder. By leading with data, UX successfully moved the business away from "gut-feeling" decisions toward a more member-centric strategy.
True operational excellence is achieved when design research is so compelling it moves the executive needle—proving that transparency isn't just a UX best practice, but a business imperative for long-term member trust.
